Which Pokemon are completely unavailable in Generation 8 games?

I know that:

Now that Generation 8 has already ended, there are still a number of Pokemon species (and regional forms) that cannot be obtained in or transferred into any Gen 8 games (Sw/Sh, BD/SP, PLA), even those that are only obtainable in LGP/E and S/V. Which Pokemon are these?

(assume that you do not transfer any Pokemon from Bank, GO, LGP/E or S/V in order for these Pokemon to be obtained and used in any Gen 8 games)
