There are plenty of Pleuros and Lepanthes that would fit those conditions but I will keep singing the praises of Scaphosepalums! These are an absolute joy to grow and are always in bloom with cool dangly spikes. Not picky at all about light. I used to think these grew a little slow but once I put them in a terrarium with better humidity, it’s normal to see several new growths and spikes every single month. And the spikes are sequential bloomers and will last for years apparently. Some of the smaller growing ones that would do awsome in those temps are the Scaphosepalum digitale, Scaphosepalum rapax, and Scaphosepalum ovulare. The swertifolium or breve (which had one spike in January and now has 14 to give you an idea of how floriferous these types can be) would also do great but are slightly larger.
Some pics for an idea of size, once these got settled in the tank which took about a month, they became absolutely loaded with spikes:
Scaph. rapax in bud
Scaph ovulare
Scaph digitale
Scaph breve
Scaph swertifolium, this is about the same size as the breve
Also the Platystele umbellata, and Lepanthopsis astrophora are very nice fuss free, always blooming minis that are easy to find. And don’t forget about the Bulbophyllums like the lasiochilum, ambrosia, and thiurum!
