I was a STEM major, and admittedly, I was disappointed that math wasn’t used much in my field (IT/engineering) except every once in awhile. I asked some of my other STEM friends, and they had similar experiences. What those higher classes did is help us think about problems in different ways.
Anyway, as my DCs begin high school in the next couple years, I wonder what alternatives to the Algebra I - Geometry/Trig - Algebra II - Calculus path is out there.
OP you posed a great and important question, but you're not thinking about it in the correct way. Math is not necessarily a strictly linear progression like what you described (and what K12 American education tries to have you believe). The "Algebra I - Geometry/Trig - Algebra II - Calculus path" as offered in school is analogous to the "meh" tasting bread, or the plain potatoes offered on the restaurant menu which makes one feel that something is missing. There are lots of other exciting choices, not only because they are different type of dish (number theory, combinatorics, probability, statistics, contest math, and all kinds of other higher level mathematics), but also because they taste really good (because they are actually cooked well). In particular, if you select any menu item with a lot of problem solving, you will find your meal very satisfying. Note that Algebra I, Geometry, and all other K12 subjects you mentioned can be taught with a lot of problem solving, but THEY ARE NOT in the current American curriculum. That is the main reason why they are boring, tasteless, and feel empty.
To your gripe about not seeing enough mathematics despite being a STEM major... I suspect that you suspect that your experience may not generalize to other STEM majors. Sure, there are many who do not use it even at all (certainly many in IT especially), but you have to agree that there must also be many jobs that use an incredible amount of math and engineering concepts. I mean SpaceX/NASA just launched its first manned mission to the ISS, which hasn't happened for 10 years! This was no easy feat at all, and many many incredible people had to solve many many difficult design, engineering, math, science, etc. type of problems.
But I digress... I'm also not saying the extremely linear K12 pathway offered to us by schools is worthless. There is a reason it's set up like that, namely that algebra is required to understand calculus, and calculus is required to understand pretty much anything in science and engineering. And geometry is also not only fundamental to our world, but it's the gateway to thinking about problems in a mathematical sense, i.e learn how to prove things for one's self (that is if they actually teach it properly, which they do not... very far from it). See here if you're curious how they screw it up:

You can't get out of learning algebra and geometry, and studying calculus. These are just the basic fundamentals needed to be successful in STEM. And by STEM I not only mean your typical IT job (which may admittedly not require much math as you related), but many of the exciting (and high paying) engineering jobs out there (i.e all the tech companies in Cali, and the other spots in the country). And if you're interested in doing research, then having a good mathematical understanding is even more critical (this includes a really solid grounding in statistics, in order to even be able to write up an experiment).
You should supplement all the K-12 above classes with real problem solving. If there is no thinking going on, then you're not doing mathematics. If there isn't a problem to solve in the classroom, then there is no point memorizing a bunch of formulas. You should be aware that many school students taking AP calculus classes have almost no problem solving ability. If they were to be asked to solve some elementary math problems (such as found in a middle school competition like MATHCOUNTS, etc.) many would have no idea even where to start. Yes, the situation is that dire.
Luckily you have endless amazing enrichment opportunities outside of the classroom and it's just a matter of choosing some. Others mentioned AoPS, which is obviously pretty amazing in terms of teaching problem solving in a challenging environment. There are lots of Youtube channels that give you a taste for cool mathematical topics (3blue1brown, Numberphile are some of the best). There are lots of high quality courses on the MIT OCW site that are completely free, and you also have many MOOCs that teach pretty much any STEM class you can think of. All of these will have ample amount of problem solving.
Remember the most important point: if you're not struggling solving a problem that you don't initially know how to do, then you are NOT doing mathematics. I will once again recommend Lockhart's Lament which I linked above, as he explains all of this in a much, much more eloquent fashion than I could even begin to.
