French doors are good in that you can see through them well enough to shoot fairly accurately.
We got a new sliding door to the deck last year. It is a large, 3 panel unit, with the middle panel being the slider. We had several estimates and people came to measure. Only the one from Lowe’s accurately assessed that the rough opening available from when the house was built in 1992 was not as high as some of the doors available, which limited us to choices without rebuilding the whole opening. So be careful with that. I guess some were 81.5” and some 82”. We ended up with a jeld-wen (?) model, and have been happy with it. The Lowe’s contractor did the installation. Would not try to do by ourselves.
As for security, I think any choice you make is a risk for breaking glass and breaking in, no matter how many locks of what type it has.
