I use Nextcloud + OnlyOffice, both self-hosted.
Free and Open Source Software

Hmm I've found some comments over the internet about it, but I must confess self-hosting is not yet for me, since I'm a newbie still :(
Any other alternative or guide you can recommend ?
Thanks in advance again
If you want some cloud syncing but also want privacy, then you will have to self-host, or pay someone to do it for you. There are some free tier Nextcloud accounts, but quite limited in storage. Disroot is one of them. If you do end up self-hosting, there are really good budgeting stacks out there:

My partner and I use Actual budget, and I can recommend it.
For any of these services, you don't even have to have a server running 24/7 if you don't add transactions live. If you do it once a day, just boot up the Docker container, store your stuff, and go about your day. But if you want constant access, you'd have to leave the server running all the time, and to access from the public network, then I recommend Tailscale.
I used to host my own nextcloud instance. It takes a bit of effort to setup and requires some maintenance. As far as self hosting goes I would grade it as easy to do. So if you like a Dropbox style option and want to try it out, you should.
But honestly I'm here to steer you towards syncthing if you go the file sync + libreoffice (or whatever) path. Once I found out about it I switched, and am happy I did.
Syncthing and maybe pro expense.
I've never used pro expense, I just searched f-droid for "finance" and looked for something using local storage.
You probably need to acknowledge that whatever you find isn't going to be a 1 for 1 replacement for your current workflow.
, and something like "pro expense"
You could just use Libreoffice/Colabora Office App and sync however. If you want it encrypted then it would need to be an e2e service. Syncthing, Proton Drive, Treaserit, or just Cypomator in front of Drive.
