Let's Encrypt SSL/TLS certificates are free, as is Apache/Nginx/Caddy to reverse proxy Nextcloud or any other solution (if a web based interface is needed). You might also need something like ngrok ( https://ngrok.com/ ) for publically accessing the instance if you're behind NAT and are hosting it on a homelab, or alternatively just put it on one of the VPSes that you're using, if you have any.
Personally i'm using a similar setup (a WireGuard VPN tunnel or two in there as well) on my pre-existing VPSes, so the effective costs are 0$ for me. And the file based approach is actually superior to any (possibly) dubious browser plugins in my eyes.
