Setting up your own wireguard vpn at home is a great option. Look up pivpn. I recommend setting the port to 443 or network time (123) to spoof your traffic and have it work everywhere
The raspi is either a small hacking tool, or a learning tool. It certainly isn’t ideal for things like nextcloud, but it is by far the coolest and most fun way to learn Linux and self hosted services. I ran emulation station, did nextcloud, pihole, pivpn, fail2ban, did robotics, learned python. I now use it for one thing - pivpn (Wireguard) and pihole to access my home network remotely
Neat
