Perfect Golf was your best option up until a month ago, now they no longer offer it because Trackman bought them (PG). TGC is your next best option, but the tour sucks, the stats suck and the guy that runs the website is a commie (straight up reads and deletes PMs from people talking about PG, deletes most content from forum that is critical).
As for a net, since you are looking at getting into sim, I would look into building a retractable cage/screen that folds/slides/lifts out of the way depending on your space. Net return with monitor is plenty fine until then.
I use kirkland (the 4 piece) balls at home. I hear the Vices crack real fast from others. I like the MG balls too, but i still have a ton of ksigs.
Visit
https://www.onlinegolftour.net (PG tour) and
https://golfsimulatorforum.com/ (the commie forum) for build ideas. Plenty in both.
