I should have commented on the White Thai Guava, That tree is coming along, in some ways reminding me of Chinese quince. In that Chinese quince (Cydonia & Pseudocydonia) leaves don't reduce as much as Chaenomeles and other smaller leaved flowering quince). The large leaves do reduce a fair amount, but still end up large. When in flower and in fruit, the visuals, especially the giant fruit make it easy to ignore the leaf size.
I do like that you started with a good size trunk and brought a tall tree down to a manageable size. Well done. I like the look of the one giant fruit hanging on the tree. Its cool.
Guava (Psidium) in general have leathery leaves that stay a bit on the large size, slightly out of proportion for bonsai. In the same family, with similar flowers but much smaller leaves and fruit, are Eugenia, the bush cherries. I find Eugenia good outdoor for summer, indoors for winter bonsai for us northern growers. Might be a better size for you once you make the move to Pennsylvania. The fruit are small, smaller than culinary cherries. There are a dozen or more species of Eugenia, all have edible fruit, though some are more edible than other. (some are tasty, some are not so much).
Actually the whole guava family has many species that have some good traits for bonsai, smaller leaves, nice flowers and edible fruit. Luma, Ugni, Jaboticaba, and many others.
