I've grown trinidad perfume and have mixed thoughts about them. I really don't care for them raw or in savory dishes, but they are FANTASTIC candied. I won't be growing them this year though. For a mild pod, poblanos/anchos are a good all-around type. I love aji habanero flavor - it reminds me of oranges, but different. You can't go wrong with a purple jalapeno, IMO. Slightly sweeter than a standard jalapeno so great flavor. They're smaller and seedier, but for me the flavor beats those factors. I picked up a tin of powdered aji panca, and will definitely grow that some time soon. I absolutely love Rosa Maria's Chile Pasilla de Oaxaca salsa, so will grow those at some point, too. I decided not to add to my peppers this year (I still have 6 overwinters, though) as I've got plenty of dried pods for now, but will definitely add to the bunch next year.
Heat levels are usually pretty subjective. What I think is mild might be hot for others and outlandish for some. If you think a jalapeno is kinda hot, these peppers will be right around there in heat - some less, some a little more.
Mild(ish) suggestions:
Anaheim type peppers - NuMex Big Jim/NuMex Joe E Parker - easy to find, good for frying and fresh. Best roasted and used in all manner of dishes.
Ancho/Poblano - same as above.
Mariachi - grew these last year - beautiful almost light tan color that ripens to deep red. Very flavorful with some bite.
If you can find any of these get them - you won't be sorry![]()
