What's some mild but flavorful peppers?

I decided to explore peppers with flavor and heat that is toned down.
Nothing hotter than Fatali
So far I discovered thunder chillie peppers - I enjoyed that a lot
Any other recommendations?
I assume you've already tried jalapeños?
How about Sugar Rush Peach.  They are flavorful with a mild/medium heat.
Peppadew comes to mind.
Not really sure what you are looking for.  You mention nothing hotter than fatalii.  Have you tried the rocotos?  They are very flavorful and I think the heat is less than fatalii.
Just a few ideas.
This is what I grow and breed for. Mostly baccatum and baccatum x chinense hybrids. If you are interested in some seeds for next season dm me.
