After connecting to Hisense 43A65H, RPi5 didn't let me go over 30Hz exactly like RPi4.
I connected RPi5 to Denon/LG monitor. No picture at all.
You make debugging more complicated than necessary. Try without AVR's. If the issue persists, provide a log.
You didn't followed the above instructions for providing a log file (incomplete, wrong log level, not on our server).
Also you didn't answered my questions, and voltage vs. wattage seems to be unknown.
Based on such incomplete information I can't help. 
CodeWould RP5 + NAS be OK?
Many users do it that way. Just make sure your NAS provides enough speed for your codecs (check Mbit/s for codecs).
Clowning around... 
Read here about Intel NUC8 firmware update:
If the error persists after firmware update, activate log level 1, reboot, and post another log.
Does your PSU provide enough wattage? Does everything work on RPi OS? If both answers are positive...
Maybe this thread helps:

Set log level permanently to value 1:

When the issue appears, login by SSH, run pastekodi to generate a log file, and post the resulting URL.
I'm more than happy to share it but seems it's too large to attach. Any suggestions?
We don't want to add that skin to our add-on server, because that would result in version mishmash. Ask at the Kodi forum.
Now I have to figure out where I would file that bug with the alsa people. Maybe it has to do with the Conexant CX20632 HDA sound chip in the HP device that is maybe not that common. Any hints where to submit that issue that the device quirks are added upstream?
I was asking a developer, who is some sort of a Linux audio guru. His answer:
If it doesn't work at ubuntu either then it's best he reports it to ubuntu folks, then they can take action.
no idea what hdajackretask is, never heard of that before
which CoreElec to try on S905D m8s plus-dvbs2x, only NE build i think have that kernel but this device is 1st gen S905D and builds suported egsists in NG which has 4.9 kernel
We don't answer CoreELEC questions here. They have their own forum.
Yeah, that was expected. You can uncomment audio_pwm_mode=1 for slightly better quality.
For good quality, buy an USB audio interface like this:

I'm an FHD guy, and I'm using RPi3B+.
Yes. If you have a look at the site from post #3, only NFO Filename and Title have those little "mandatory stars". The rest is optional.
Yes, it's the same for your Bluetooth device.
On Windows you can use PuTTY for remote SSH access. Of course RPi has to be connected to your router to use SSH. On your PC PuTTY will establish a connection to your router, and from there to your RPi.
Obviously there are many optional tags you could add (see link at post #3).
So what's the question? Is the poster invisible? If so, take a working JPG, and analyze its density (PPI value). Then convert the non-working JPG to the same density.
