Mullvad. The only VPN company I actually trust.

It's important though that Mullvad doesn't do port forwarding; you won't be able to seed effectively

I pay for proton. It works. I’m not as security conscious as I should be but it’s pretty much a set and forget thing aside from changing ports.

Then you probably don't want a free service that costs money to run where they can only make money by converting most users to paid or monetizing your information in a country where you are unlikely to have an attorney whilst operating what amounts to a honeypot for every government on earth.

That said protonvpn seems reputable

That's a fair point that I arrived at once I put half a second of thought into what I was actually asking.

Proton VPN has port forwarding that lets you seed torrents.
