In Mail 16.0 (3774.500.171.1.1) and on a Mac using mac14.4.1 old mail which had been read a long time ago and also recent mail which I’ve just read is coming up marked as unread.
Is this a known bug or is it, as feared, just a mistake on my part?
I’m grateful for any and all suggestions and I’ve already gotten many, unhelpful, ones elsewhere. So in advance thanks.

That is not likely to be literally caused by versions of Apple Mac Mail.
More likely you have/had mail set up somewhere with POP (which assumes ONE reader) and all should be IMAP (assumes multiple readers). Another weird difference is that POP sends ALL messages to Mail, IMAP sends ONLY Headers, and downloads the rest (or not) when you request them.
IMAP correctly marks a message Read on any device as Read everywhere. POP does not understand that.

Thanks for the swift reply and the help.
As I read your message I wondered why it would be that I'm just seeing this now instead of a week or 10-30 years ago. (I can't remember when I first started to receive emails)
If something was still hidden and still set to POP I think I might've seen this before.
if makes my head hurt to re-enact what if this one was this way, and that one was that way, and then it got changed to the other way...
Just check all your mail settings on all your devices are set to IMAP
