Just run things and find out. It really depends on your network and environment. Take note when things act up or slow down and scale back.

I usually have over 1,100 torrents seeding but maybe a dozen or so are active at a time. Maybe more sometimes, I don’t watch it as closely as I used to.

A few times I’ve added hundreds of movies at once by importing IMDb lists and experienced network errors. I had to download them in batches.

PC!

I have a Steam Deck and Switch too. The only reason I got an Xbox was for NHL games. There hasn’t been an NHL game on PC since 09.

I just never cared. People treat their IP like some secret identity. It’s not as precious as some people think. I go to trackers without VPN all the time. My transmission client is always behind a VPN.
