For a normal hardwood desk/table top, if you band the edges with a strip of wood, it will not cope well with wood movement. Particle board doesn't suffer from this problem unless you get it wet, at which point you have bigger issues. What about plywood, can you apply edge banding without worrying about it separating from panel?

Plywood is more dimensionally stable so yes, edge banding works as well or better on ply than on particleboard / chipboard.
Edge banding is almost synonymous with plywood construction; woodworking guides going back to the 50s and possibly earlier talk about hiding the "unsightly" edges.
There are other methods that can be used to hide the edge of plywood that are worth considering as an option to conventional edge banding:

Where you aren't using iron-on edging you need some way to clamp the edge successfully. They make specialised edge-clamping C-clamps for just this purpose, but these two homemade alternatives work just was well:

Wouldn't that shape of clamp block tend to get glued in place by squeeze-out? Maybe some plastic or tape in between would be a good idea. Commented Dec 21, 2019 at 12:11

@DaveInCaz, yes they'd need to be protected from glue somehow. Covering in packing tape is one good option, another is finishing them as glue doesn't stick to finish. Just waxing the bare wood is usually enough.– GraphusCommented Dec 23, 2019 at 12:41
I edge band plywood for everything except cabinets for the shop. I have used the heat sensitive, iron on banding as well as shop made, glue on banding. Both work well. The iron on banding is not as durable as the shop made stuff, but it is much easier.
For trimming the heat sensitive banding, I use the cutter from FastCap. For trimming the thicker shop made stuff, I use a router in a table with a high fence and a trim bit.
Plywood essentially doesn't move with humidity changes. Solid edge banding may, but the motion would be across the grain, so if the grain runs along the edge (as is usual) the change is a small percentage of a small distance and doesn't produce enough force to bother the glue. So, yes, this is a good and common technique.
If you are making shelves or similar, note that the edge banding doesn't have to be flush with the plywood. Letting it extend down a bit is a simple way to give more "visual weight" to thin material.
