Poolesville, then a feeder into Churchill is probably a better option than others. At least at these two schools, the programs are good for both magnet / non-magnet students and are less likely to be messed with.
The issue is not that there aren't good programs DCC. The issue is that it's a crapshoot. School boundaries will likely change and most choice programs went lottery.

Notice MCPS was very careful not to publish actual boundary maps and you'll have to reference the boundary analysis tool.

Overview:

It was pretty sneaky how MCPS solicited input. It was done during the height of covid with little fanfare (ex. announcement by most PTA's) and they only showed the tool, not specific proposals of what plans MCPS had for specific boundary changes. The way MCPS works is they'll probably make a last-minute release of actual boundaries in a very short time-period to minimize the possibility of delay. Typically there's been "for show" discussions but an option seems to be pre-selected with little chance for input from families living in the area. Expect "talk to the hand" versus "interactive discourse" when it comes to MCPS boundaries.
The problem is the current BOE. Only two incumbents were replaced this year and it's still very "equity" over "equality". You could very well buy a house in a school boundary and find out it's been boundary swapped down the road. Same goes for McKnight and the lottery-based magnet under her tenure (as well as financial management and overall leadership) has been a disaster, imho. Until Wolfe is voted out and the other legacy board members change, it will be difficult to fire McKnight.
There are people on this thread who will push you towards Takoma Park (especially the "blair envy" person). If you want specifics about particular schools as a non-magnet/non-choice home school program, I would Google your school name and Profile PDF. For safety, I would avoid a UofMD score under 80%, or a has a suspension rate in Middle or Elementary school.
