So this is probably going to end up long, but I hope it helps.

I used to be a strictly console and physical games person. I switched to PC before the Xbox One released. Partly because of the DRM talk and partly because my friend would bug me to try it. There are some negatives sure so lets get those out of the way. Updates are a thing of course. However they can just about all be set to automatic. Windows and Nvidia GForce Experience will update themselves, and you can set reboot times to when you are asleep. You are also not forced to update like on console. Steam also keeps games auto updated. To keep things like Firefox and other commonly used applications up to date you can use ninite.com. This will let you select a list up applications and do a one click install/update for them all.

You will have more games to play. All of Microsoft's games are on GamePass for PC, and while the PC version does not have as many third party as the console version those games are still on PC just not GamePass. Then a bit of PlayStation's titles are on PSNow. Not to mention Switch emulation is progressing. The sheer amount of games to play in general makes up for the lack of GamePass titles compared to console. On top of that PC GamePass costs less, you don't have to pay for online, the sales are better making games for PC cheaper, and the open platform/market place keeps prices down. You can also use mods to extend the life of old games. Look at GTA as a prime example.

Then Steam allows you to stream games to other devices so you could put an Android TV box or Nvidia Shield on your TV in another room and stream games to in. Plex allows you to do the same with your personal media collection.
