80, 443 for HTTP/S, and 587 for a VPN service. Reason being that I travel frequently, and often have to connect through a bunch of different networks, Airport WiFi, mobile roaming, hotel WiFi, etc. and you never know the kinds of network restrictions they impose on their pipes.
80 and 443 is least likely to be dropped, while 587 is a common SMTP port that could make it through most networks.

I'd if I could, but CGNAT.
This year I started using DynDNS with only my IPv6 address since IPv4 is behind CGNAT and it actually works quite well nowadays
What do you mean works? Like you could access from everywhere some services like Plex or Nextcloud?
yes just like with a static IPv4
Ok, I'm not sure of how exactly this works, but I'm gonna check it out since I have IPv6 addresses.
Just to be clear, even from IPv4 only can access my exposed services?
If you expose ports on IPv4 or IPv6 (port forwarding) anyone can access the service behind these ports if they know your address but so do you too
I run a few services that require ports to be open. Everything that can go behind a reverse proxy does so. But there's some that can't and that's OK.
ipv6 and reverse proxied. yes.
The only port I open is for wireguard. That way I can access all services on my LAN. Wireguard is also very secure and requires keys based authentication so is hard to brute. It also allows me to secure myself if I ever need to join WiFi or an untrusted network
I have one for OpenVPN and that's it.
I use Remote Desktop, BitTorrent, and play games, so I need some things open for that. I used to be super paranoid about hackers and viruses and shit like that, but it's not like those things are looking for regular, everyday users and even if they did get in my system, I don't keep anything important on my computer so I can just wipe it all out and reinstall everything.
