Makes sense! And honestly, this sort of thing is really subjective to the reader and the writer. For me, I don't like a lot of dialogue tags, or when you like... vary them. As a reader, I can tell when you constantly try to make a dialogue tag a different type of action (ie: yelled, hissed, imparted, etc etc). The best advice I ever received was: "Just used said/says". People gloss right over this word and don't even notice it, and it's true. So my go to is to use mostly 'says' and 'replies', and then a different tag when I really need/want to emphasize a tone, or a change in tone.

As far as the speech itself-- I don't think you need to really worry about if it's 'boring' or not? Some character, for example, have a boring cadence. I think the goal for dialogue really should just be... "Is this in character?".

If you're feeling weird about a work, just ask someone to look over it! We're our own worst critics and like 99% of the time there isn't actually anything wrong with it!
