Caladium has done well for me when nothing else works.

The only way to find plants that are readily available in local nurseries is for you to go to them - from way out here it is hard for forum people to guess. I don't know about the big box stores, where I gather a lot of people buy plants, but at nurseries you are likely to find people with a wealth of good, locally applicable advice, along with the plants!

ferns & caladiums. I've tried others shade loving plants, these fill the pots nicely.

You will find that one lysmachia per pot is more than adequate, and certainly that 3 is too many! They spread quickly & more than one will dominate the root system of whatever else you put in the pot. Take out 2 from each pot & find somewhere else for them. You won't regret it!

I'd look at various Carex or 'sedge' plants. They're mostly evergreen grass type plants which do well in shade. See Carex pendula and Carex flagellifera 'Kiwi' on the link below. Also, liriope is a good structural, strappy plant to contrast with the chartreuse of lysmachia. Then, you could add one calendula bulb per pot for color, perhaps some daffs or tulips for color before the calendula comes up in spring It would be a nice mix.
