Gallery still crap, can't delete albums.
Ok, the gallery app maybe won't win design awards. But it works reliably in my experience. I only recently found out that you can even trim videos with it.
The nice thing is that there are many good alternatives that you can install - there's something to suit every taste. Here in the forum the following gallery alternatives are often mentioned, maybe you want to give them a try:
Aves, Fossify Gallery, Gallery, Ente Photos and others (I have certainly forgotten some). You can also use Pixel Camera and Google Photos if you like.
I personally can recommend Aves Libre (available on Accrescent f.e.) and Gallery.
Screen Recordings are not shown in Gallery or Google Photo, and also the recordings hang for the first 3-5 secs in picture when playing.
...
The screen recordings already worked good in the past. Today 3/5 recordings are stuck at the begin for some sec. Mostly I record short 5-20sec clips from YouTube app.
Strange. I use Screen Recording regularly and it works fine for me - the videos are saved under your device> Movies.
I have also tried to reproduce the bugs you described. Screen recording of YouTube videos does not cause any problems in my case - neither in image nor in audio (i recorded several clips up to 7min., 720p - 2160p, Pixel 9 Pro, version 2025062700, PipePipe version 4.5.0). Maybe it's a hardware issue, as matchboxbananasynergy already stated.
Many other Google Pixel features are still missing. That's pretty misfortune, because this OS is exactly for expensive pixel devices.
I think that explains the project's focus quite well:
GrapheneOS is a privacy and security focused mobile OS with Android app compatibility developed as a non-profit open source project.

In addition, GOS offers - in my opinion - an astonishingly high level of functionality that is no much different from a standard OS. What features are you missing exactly, could you elaborate?
I need to reboot my device pretty often because of "Updates available" and a long period of "optimizing apps" but I don't know if anything is changed or improved at all.
So everyone looks at things differently - I'm always happy about updates because I think that (security) issues are being fixed and functionalities are being improved.
There is a reason why GrapheneOS takes a different aproach on "optimizing apps" which has the downside that optimization after reboot takes longer compared to standard Android:
GrapheneOS optimizes (compiles) apps at install time and app/OS update time. Standard Android does it dynamically in-memory while you use the app, which is a security weakness. It's listed in https://grapheneos.org/features#exploit-mitigations
