All 4 work and have there pros and cons.
Waxfoundation needs to be embedded vor nailed to the top.
If you just nail it (hooked foundation) thats a quite nice way, sometimes you break a wedge during replacement.
If you use groved top and bottom bar and just snap the foundation in, thats the easiest way, sometimes leading to warped comb. The main problem with wax foundation is not the inserting, but the removal and cleaning. If you can just cut it out like foundationless, thats the beat way.
Foundationless got the problem, that bees draw foundation towards the gravity, if your hives are a little out of balance they draw the end of the comb right beside your bottom bar or into the next frame. Sometimes they just draw multiple frames into one block.
It takes a lot if tweeking. But if you have the time to do so it is a very convenient way.
Plastic frames vor plastic foundation, is very convenient.
The frames have lots of holes for SHB to hide, plastic foundation is very easy to be die coated.
But apart from that, it is wax, put in, enjoy. Don't get the cheap stuff, but get the man lake, Acorn or Pierce with deeper cells and it is fun.
But plastic really only works perfect if you have strong hives. Sometimes weaker hives struggle, --> make new hives by creating shook swarms.
Today i would always go, foundationless, wired fountion to snap in or plastic.
