Hardware Selection for Aerial Mapping Project

Hey everyone, firstly if this is in the wrong topic sorry and let me know where I should ask about this sort of thing.
I’m currently undergoing a project of creating an aerial mapping capable fixed wing plane.
Also my plane lingo is very poor (sorry in advance), however I have worked on FPV quads in the past and am familiar with Betaflight software and general RC stuff.

I’m looking for suggestions on the following areas, as well as overall tips:

  1. Flying wing vs. body or ‘standard’ plane shape, as well as pusher config or location of motor(s)?
  2. Camera selection for the purpose of relatively small scale aerial mapping / photogrammetry, I’ve been looking at cameras and have found a second hand Sony A6100 for about $700 AUD, I have seen some comments surrounding global shutter being better for aerial mapping as it reduces rolling shutter, however any cameras I could find with global shutter were far too expensive for my project.
  3. Software / Hardware for the wing, what FC / GPS / Motors / Prop sizes do people recommend for autonomous flight for mapping, as well as a camera trigger setup for taking photos at set points along the route. Also a system for capturing GPS data at the moment of each photo for mapping softwares. Along with this I plan on using Ardupilot as it seems like the most supported software for my purposes.
  4. I have managed to install WebODM (Open Drone Map) for the purpose of combining images into a map, is this sufficient or is there alternative ‘better’ software?

Thanks for any advice on these specific topics or just general pointers / advice etc.

Cheers
