I use platforms with half toe clips (no strap). They are easy to get into and feel like there is nothing obstructing getting out. I have never fallen because I could not get out, so I don't have any anxiety. I also tore my ACL skiing some years ago, and don't want to risk re-injury.
First, I used plain athletic shoes, but people in the club kept telling me about how much more power you have with a stiff sole. So, I bought a pair of cycling shoes at a PI outlet store and use them with the half toe clips, but no cleat. It is also easier to walk in them. The mountain bike soles are a little too thick to fit well in the half toe clips. Anyway, that worked even better then the athletic shoes. So, that's my recommendation.
