Stopping selfhosting some applications?

I've started self-hosting quite some services over the years, stopped with a couple as well. There is something special about doing things yourself, and running your own software and not giving away your data is one part in that. I even enjoy finding new services ready to be self-hosted on pages like awesome self-hosted. There is software for everything these days and at some point I was wondering if it was the best solution.

Stuff I'm running

To give you some context on what software I don't want to self-host anymore, here are some services I use a lot or are interesting to mention:

1. Home automation - Homeassistant
2. Ad blocking - Pihole
3. File sync - Syncthing & DS file
4. Recipe manager - Mealie previous Tandoor
5. Relations manager - Monica
6. Automations - Custom software & N8N
7. Feed reader - Miniflux
8. To-do list: Todoist
9. Obsidian

Most services "do stuff", like turning on the vacuum, gathering feeds and keeping track of new ones. Some do a little like Monica with the reminders for birthdays. Some do almost nothing but just store data, not even managing drives & backups, just provide an interface to change data. Like recipe managers (I know it can do a lot more, but this is just where I'm using it for). At some point in time I saw someone use a simple file with all of his to-do, and it made me wonder I wasn't overengineering a lot of things with software. Todoist gives a lot of structure in my life with reminders, smart recurring tasks and ease of use. But for something like storing recipes, maybe I could just store it in a file.

The plan

Move my recipes and contact information to my notes using markdown files. Every recipe could be a file, sprinkle some frontmatter in for labels, tags and the structured information. What about the recipe reviews or when I ate what? I just don't care. And what about the birthday reminders? I have to figure out something for that, probably just a list with references to the person in Markdown and a script that sends me the reminders. I'll start with the recipe list and work towards automating the reminders first, before going moving away from Monica.
