As for original designs from 3P we have a few, Orion is a really popular one, pairs with his mate Hegemon (but I'm not a big fan of Hegemon honestly). People talk crap on Orion but I'm a big fan of him.
Planet X is making a WFC one which looks really dope, so if Wf/FoC is your thing they're a trusted company for the most part.
There's also Battle Sentinel from Maketoys, its got a smaller figure that power armours into a big version of Laser Optimus. It's pretty old now though, and a lot of people get put off by the whole parts forming thing, but power armour is a taste that a lot of people have for 80s super robot anime so if that's your thing its worth a look.
Other than that, most of the others I can think of are all MP Scale, and besides that most 3P toys in general are of more "literally who" characters that are less likely to get official treatment unlike Optimus and Bumblebee etc.
