I had the exact same experience with that model. The screen eventually cracked (I think I had it in a backpack that I was a bit too rough with). It was easy enough to replace the screen with one I found on AliExpress, but unfortunately the replacement then cracked a few weeks later. I don’t know whether it was because the replacement screen was poor quality or because once I had taken the device apart the screen was less protected, but I figured I wasn’t going to throw good money after bad. I ended up getting a second hand Kobo Aura on eBay which has served me well.

eReaders have gotten some new features like backlights but I don’t think the technology has fundamentally moved on all that much.

I run OpenMediaVault as it brings plenty of nice features together like SMART disk monitoring, resource usage monitoring, easy RAID creation, FTP/SSH/browser access, etc. You don’t strictly need it (or TrueNAS, UnRAID, etc) but it’s nice. Unlike TrueNAS and others, OMV seems easier to install on an existing Linux distribution (I run it on Debian).

For important stuff that you really don’t want to lose, you probably want to set up a RAID array of some description. The various NAS solutions like OMV or TrueNAS will make that easier but you can do it without them. It does mean you’ll want a lot of storage (disks will probably be the most expensive part of your setup) and you’ll want your PC to be able to accommodate multiple hard drives (I would think at least 4) particularly if you want to run a RAID.

Jellyfin is good for streaming. Beyond that I don’t know much about sailing the seas at scale.

Nextcloud is decent for file storage and has a few good addons that allow you to use it to selfhost calendars, contact, Joplin notes, etc.

Paperless-ngx is a good solution for digitising documents.

Yes there are plenty of different solutions out there but after a while you come to see that as a feature rather than a bug. Selfhosting definitely carries a lot more friction than outsourcing it all to Google, so it’s something you need to get used to. It helps if you can view the process itself as a hobby rather than a chore and embrace the fact that you will need to learn a lot to make it work.

I haven’t used it but the Bangle.js 2 looks almost perfect for a cheap, open/hackable GPS smartwatch. I’m always surprised I don’t hear more about it. Leads me to believe it’s not as good as it seems, but very interested to hear if anyone has real life experience of it.

Currently I just stick with my Garmin. I’d prefer something more open but it’s good at what it does and pretty durable.
