I got a recumbent in the mid-1990s due to hand pain on a road bike. The bent with underseat steering solved that, and rode well in flatland, but I needed to go back to an upright bike once I relocated to hills, perhaps the lower gearing available now would have solved. My 'bent was not a trike, but a LWB Linear two-wheeler, and the riding position was upright with only a bit of recline in seat and legs forward. Very similar layout to Avatar 2000, and Ryan/Longbikes Vanguard, both with underseat steering. I could sit on it comfortably when stopped to eat my lunch. I toured on it with a trailer. So very easy to get on an off, perhaps better than a low 'bent trike. Mine also folded for transport, but not something to do frequently, but available. I don't know if weakness or balance will prevent the OP from using a 'bent bike versus a trike.
