Plus they always try to hide how stuff works behind the scenes so that day that upgrade script has a bug and fails, it’s hard to revert to a working stage.
Yunohost is creating backups for apps that are being updated. If update fails, it automatically reverts. Yes, it works, I checked.
those projects get eventually abandoned,
Yunohost is here for years now, and it does not look like it will be abondoned any time soon.
Nextcloud is hard to install in manual way (even sometimes with Docker). As far I know, both Snap and Yunohost versions of Nextcloud are solid. I used Snap version on the cheapest Linode VPS, and it worked fine, especially when I doubled the SWAP to 1 GB. Now I use Yunohost version and I have only good time with it. It is super stable, fast and reliable. I used Nextcloud_ynh on HP 800 Mini G3 with i5-6500t and now on Asrock Mini PC with Ryzen 7 5700g. It is working just great.
If you don’t want to use Nextcloud, you ca install Vikunja for kanban and tasks. For notes Hedgedoc can be great.
I think you can go with Yunohost. It is easy to start selfhosting and exposing services to the web. I use it for more than a year, and it is super cool. Especially I love the fact, that it is easy for newcomers, but also it is opened for customisation for more pro users. Yunohost provides domain with ddns, Fail2Ban and tells which ports should be opened (80 and 443 is all you need, maybe another one for ssh). It also provides SSO for hiding services that do not use authentication.
Wallabag! I am using it for more than a year and it is great
