I think, it's really good, that @thunderbird integrated GnuPG, but it's really annoying, that I still have to manually disable encryption, when I write an e-mail to a contact, who doesn't use GPG (which are unfortunately still quite a few).
In that regard #Enigmail worked a lot better.

Thunderbird 115 includes new settings that you could use to get the behavior you prefer. Go to global settings (not account settings), privacy&security, scroll to the bottom, section "Email End-To-End-Encryption, Automatic Use of Encryption". There are three checkboxes, set them as you prefer.
(And just to clarify, while Thunderbird integrated OpenPGP compatible encryption, it usually doesn't use GnuPG, only can optionally use GnuPG for some operations.)
The following works for me to get a fixed width font:
When viewing an email, in the header section, there are buttons labeled "reply, forward, archive" etc. On the right hand side, click the button labeled "more" which opens a menu. Select "message body as, plain text".
If you want to have a fixed width font when composing: Go to account settings, "Composition & Addressing", and ensure "compose messages in HTML format" is not checked.
Maybe that's a stupid suggestion, but...
Could you simply copy/paste between Thunderbird and your external editor?
If you configure Thunderbird to use plain text (as described in previous toot), I'd hope nothing gets lost?

The reason I think this should be a native feature and not addon is this addon for TB:

I do not know much about addons (or more like know almost nothing) but this does give a hint that either:
Because having to run external program is a bit too much at least for me. Not too use friendly at leastβ¦
