I like my Kubernetes setup at work. It runs Nextcloud, Mattermost, GitLab, company website, several embedded firmware OTA update sites, a few internal apps. Nextcloud was pretty easy to install on it with Helm, just a single command line and a yaml file to specify domain, settings, etc. I had some teething issues in my early setup where the database would get wiped inexplicably, but it's been running smooth for years now. (Yes, I know, bad juju running databases on Kubernetes...I'm used to it and it mostly works)

For me Nextcloud AIO works. Still I don't like how "unstable" NC is. There's always something that does not work in any setup. Wish it was more stable or there would be a better alternative. For me it's videos. But only those that are MP4 and have their moov atom at the end of the file. They can't be played.

It's a headache. Set up Ente Photos just for that. Good side effect is that the images from my family and myself are stored E2EE encrypted on the self hosted Ente Photos instance.

Proxmox > Debian Container > Apache, MariaDB, PHP is the way

I used or it used me for a couple of years. Then while looking for a replacement I found the snap version. I installed it in a fresh Ubuntu VM and it just works.
