I'm not a nextcloud user but have a homelab and use traefik for my reverse proxy which is configured to use letsencrypt dns challenges to issue wildcard certificates. I use cloudflares free plan to manage dns for my domains, although the registrar is different. This has been a set it and forgot solution for the last several years.

Let's Encrypt cert renewal comes out of the box on traefik? I haven't kept up with it. I'm on a similar set and forget schedule with configured nginx and some crowdsec stuff, but the API change ended up killing off an afternoon of my time.

Yep, it supports ACME (Let's Encrypt) out the box and many DNS providers too. I mainly use namecheap as my registrar but configure Cloudflare as my DNS resolver; I find this easier from a configuration perspective and CF APIs have been stable for me so far.

Traefik (by default) will attempt certificate renewal 30 days before expiry. Perhaps the defaults will change if the lifetime becomes 45 days. I don't think it's possible to override this value, without adjusting the certificate expiry days, but I've never felt the need to adjust it.
