Another route is to go serverless and use DecSync. Thunderbird (or Evolution) will sync with the Android app (F-Droid available) and your Cal, your Cards, and tasks, and even RSS will be replicated on the other peers. https://github.com/39aldo39/DecSync

Leave out the GNOME bit. It would be nicer that way. Look at Synching, and DecSync built on top of it for example: https://github.com/39aldo39/DecSync

How much would you be willing to pay for it? I provide Matrix hosting (as well as XMPP and ActivityPub Mastodon) on Communick [0]. At the moment I'm more focused on taking these services to offer custom domain hosting, and personally I've been staying away from servers and using DecSync [1] + syncthing to get my calendars and contacts on my devices [2], so I haven't thought about adding a DAV server to the mix on Communick. But if you tell me there is any actual demand, I would definitely consider it.

I wrote a bit about it at a blog post [0]. My idea is to substitute the "cloud" (i.e, your data and applications running on someone else's computers) for a "lake" of your own devices where you can replicate and synchronize the data, and use native free applications for each of the devices that you have. So, for hardware - Workstations: Linux - Mobile: /e/OS [1] For software: - GDrive -> Syncthing for the documents, LibreOffice on workstations, simple document viewers on mobile - Email: My own domain, service provided by namecheap, costs ~20€/year. - Contacts, Calendar -> Syncthing to synchonize the files between the devices, and DecSync [2] as a calendar provider on thunderbird (workstation) and k-mail (mobile) - App Store: F-Droid for most software, and the odd exception (Berlin ticket for public transportation) that is not F/OSS I use t

he /e/OS store (which proxies some of the apps from Google into their own store) - Maps: MagicEarth (works well, uses OSM data, can do navigation decently and allows to choose download maps to keep offline). One of these days I will try again to self-host a tiling server, but I'm not sure what I would do for navigation. - Messaging: Matrix/Element is my main client, I also have XMPP. Both are hosted by communick, the "professional managed service" that I run [3]. I also have Telegram (FOSS client) on mobile, but I've been meaning to implement the bridge on communick so that I can ditch the client. I use hangouts only on the computer if and only if the other party is not available on the preferred methods. - Search: Brave search is working well. I preferred Brave over DDG because Brave is building their own index. If you think your queries are not giving you good results, you can turn on "Google mixing", where they make a (proxied) query to Google and show their results mixed with their own.

shoutout to DecSync (https://github.com/39aldo39/DecSync) to use Syncthing with your CalDAV/CardDAV contacts/calendars/tasks and sync local RSS feeds across devices. I don't really use nextcloud anymore for stuff that is only for myself and does not need to be shared

It's easy to forget that sometimes you don't really need to host things. I used to run a Next Cloud server for syncing my documents, contacts, and calendar with all my devices. I'd rarely use a device that was not mine to access those things. I've switched to Syncthing (https://syncthing.net/) and DecSync (https://github.com/39aldo39/DecSync) and that's replaced 95% of what Next Cloud did for me. Your use case might differ from mine quite a bit, but for me it was the best way to go. No server to babysit and everything "Just Works™".
