Suggestion for simpler software than *arr (Radarr, Sonarr) to use with Jellyfin

I've migrated away from Plex to Jellyfin recently. Jellyfin runs as a docker container on my Synology NAS. I've been happy with the setup and I decided to explore more automation tools, and of course Radarr, Sonarr etc. come as recommended.

Disclaimer: I'm a technical person capable of managing these apps (+ also write software). I followed the installation guides and also searched online for answers.

I am providing this detailed description of my usage just for context, so it's clear that I've tried my best. If you don't feel like reading it, skip to TL;DR

I used Sonarr + Radarr about a month back, but had them running on my local machine. My goal then was to make my media library work well with Jellyfin (metadata):

• unify folder structure
• provide TMDB IDs to folder names.

It went fine, and I managed to hit both of these goals, but I had to do a lot of digging in to figure out where to click in UI to do what I needed to do. I don't mean any shade to all the volunteers and developers for *arr apps, but honestly, the UX/UI is very confusing. If you're starting out, it's not very apparent what the software is good for.

Fast-forward to few weeks later: I figured it'd be nice to streamline the Jellyfin setup. My next goal was to have ability to download stuff easily and have it moved to correct media folder automatically, with correct naming (again, for easier metadata discovery).

These were the steps I've taken at first:

1. Install Sonarr to my NAS.
2. Import the library as it is, since my metadata was 99% correct already.
3. Learn about indexers. Figured I'd need Prowlarr to manage this easily
4. Install Prowlarr. Still don't know what usenet is but OK, I can work with this. Used different kind of indexers.
5. Find out Synology Download station cannot be easily used as a download client for Sonarr. Install qbittorrent. I actually like it.
6. Manage to integrate Prowlarr + Sonarr + download client. Searching for new content, automatic download and moving the content to correct folder seems to work, yay.
7. Now, I'm thinking to do the same with Radarr. Figured it should be easier since Prowlarr is installed, as well as download client is ready.
8. Import media library to Radarr
9. Set up indexer via Prowlarr for Radarr. For some reason it's not showing up 🤔
10. Search online, find out that I need to go to Prowlarr and tag my indexer with tag "Movies" specifically to have it appear in Radarr. Kinda confusing IMO.
11. Integration with download client is set up.
12. Now, I assume it might be my NAS running a bit lower on resources (2GB RAM + Intel CPU), as I now have several applications running on it - the apps seem kinda sluggish. Radarr is still probably pulling down the metadata... so I will wait
13. For some reason, I start getting weird errors during import in Radarr (database locked). Hm! maybe it's because I'm doing too many things at once?
14. Sonarr stops working, I just see "Failed to load series from API" when trying to use it. Restarting the container does not help.

It's at this point I decide, that all of this feels like too much. I know there's probably some misconfiguration somewhere, or something I haven't followed, but having it now broken just after setting it up, I feel defeated.

TL;DR: I'd like to avoid using *arr apps if possible and would like to have something simpler. Is there some software, which I could just point to my download folders (TV, movies), have it pick up automatically after it's downloaded and moved to correct media folder with the appropriate naming structure?

(Searching content from the app interface is nice, as well as monitoring content. But I feel like I could do without it and rather avoid the complexity)
