Port Forwarding - Should I? and which VPN?

Ahoy! I know this has been asked a lot already, I've been following up and doing some research online but I'm still confused. Sorry.

1-I'm not exactly tech savvy. (Ok. I'm thick as a brick) 2-I'm a very casual BitTorrent user. I'll go months without torrenting.

3-I do stream more frequently.

4-I travel often, meaning I don't often have admin access to the networks I connect to

I currently have Nord. I heard it's no longer as trusted as it used to, and since my subscription is ending I'm wondering if I should jump ship.

I read I should be using Port Forwarding, and I get the concept of it somewhat but I'm still not sure if I need it (considering my casual torrent use, so far... I've been ok?), and also, I have no idea how to set that up. (would #4 be a problem?).

Now, VPN: Mullvad, AirVPN, and Proton seem to be the most reliable ones. Is that right?

Air has good pricing atm, and port forwarding. I heard it's not too user friendly though? (#1)

Mullvad seems to have a solid rep. but no port forwarding (It used to? Their website doesn't say much unless I create an account?)

Proton: has PF, seems good too

Or should I just stick with Nord?

TLDR which VPN should I go for considering 1,2,3,4, and should I consider port forwarding in my decision?

Thanks
