It is possible to periodically clean the grinder by using a product called Grindz, but that requirement can be avoided if you limit yourself to less oily medium or to light roasts; use other brewing methods when you want a dark roast, e.g., Aeropress or a SCA-certified brewer.
I have enjoyed whole beans from Black Rifle Coffee, Electric City Roasting, and others, but find the most economical way to purchase whole beans is through Costco. While their in-warehouse selection is limited, they offer many more options on-line.
If you buy largers bags of whole beans, you might like to use a vacuum-sealing storage container, to keep the beans fresh longer. I use containers made by Airscape, available in different sizes from amazon.
I have been using dark roast beans in my Jura ENA8 for 4 years. No problems at all. I use La Colombe dark roast and it's my absolute favorite. I clean and maintain the Jura according to the manufacturer's instructions (which doesn't include using Grindz or anything like it) and I've had zero issues.
