Is compatible with both. The crucial thing is that it is formatted with exFAT.
You can take any USB 3.0 hard drive and format it via the console menu, as well as on the PC/notebook.
I used it like a madman on the Ps4 for 3 years. No problems at all.
The PS4 is now with this external hard drive at my brother's. Since November, since I now have the Ps5.
I can't say anything about the external hard drive constellation with the PS5 from my own experience, but I can only confirm what you wrote.
Yes, however, for PS5 games, the console requires the game to be on the console's hard drive. This means that you have to move the game if you want to play it. Unlike PS4 games, the PS5 console can play the games directly from the external hard drive.
Yep, you can currently only save and play PS4 games on your hard drive, it doesn't work with PS5 games (whatever Sony is up to).
And just for understanding, this is an HDD and not an SSD.
Yes it works, PS4 games are automatically installed on the Seagate Game Drive, PS5 games can only be installed on the internal PS5 SSD and not on the Seagate Game Drive.
Yes, since the PS5 update 21.01-03.00.00, PS5 games can also be stored on the external hard drive. However, they cannot be played from there. Before playing, they must be moved back to the internal hard disk. PS4 games can also be played from the external hard disk.
As far as I know, only PS4 games can be loaded from an external hard drive with the PS5. PS5 games have to be loaded internally. I read that here:

Yes and no. The PS5 recognises external hard drives and all PS4 games installed on them can be started directly, but PS5 games cannot currently be installed on external drives. The memory of the PS5 can then be expanded later via the built-in M.2 slot, but this is currently still deactivated.
The hard disk is only intended to store the data of the games. The game scores and personalised data remain stored on the PS or on the Internet. In order to use them, you must log in to the new PS and possibly load the personal data into the online storage beforehand.
This hard disk is primarily intended for expanding the internal memory line.
