all monitors have some sort of antiglare coating so its not an issue.
the Gigabyte G27Q has built in speakers and does 144hz so it should fit your requirements.
the built in speakers of any monitor are going to be quite awful and i would recommend using separate speakers or headphones instead but if thats not possible the built in speaker are still a bit better than no sound at all.
you want top of the line specs for entry level prices, thats not going to happen.
even the cheaper options like the Hisense U7K are near 1000€ and at that price you might as well spend a bit more and get a LG C2/3 which is the best TV for gaming.
any TV for 300€ is going to be more or less awful for gaming so at at that price point i would recommend a 1440p gaming monitor like the LG 27GP850 or Gigabyte G27Q.
i have heard mikrotik makes pretty good routers, you could also install pfsense/opnsense on pretty much any PC to use it as a router. there are also manufacturers like netgate or protectli that make hardware for pfsense/opnsense.
that thing is beyond fucked a big part of the die has come off.
this kind of damage usually happens when a soldered IHS is taken off without melting the solder but this CPU has no heatspreader and the TIM between the die and cooler should be normal paste.
another way this could happen is that a high side mosfet on the vrm failed closed and applied 12V directly to the core causing enough damage to crack it, but thats only possible if the board was dead before you took the heatsink off.

use CrystalDiskMark to benchmark the ssd, the readings from task manager are going to be all over the place.
install crystaldiskmark with:
winget add CrystalDewWorld.CrystalDiskMark
normal behavior, the zen+ memory controller is not very good and is limited to 3400-3600Mbps
you can apply the xmp profile and then manually lower the memory speed until it is stable, to check for stability run a memory test, use testmem5 and hci memtest.

all USB ports provide 5V by default, the phone might charge slower from a ps5 due to it not providing as much current but otherwise there is no difference.
the battery not lasting as long is unrelated.
the LG is overall a bit better than the gigabyte monitor but it does not have built in speakers.
