axisfoils.com/collections/front-wings?page=1That aside, you should get a spitfire IMO, everything else is too advanced if you can't gybe yet.
Here is a simplification
* You are in 1, moving to 2, only worry about 3 once you are tired with 2 and know that you want more of something specific.
* Experiment with tails before changing front foils, they make a huge difference.

This is a great simplification but as another beginner I have the same confusion about the tails.
I'm only a season into the foiling journey having come from windsurfing to windfoiling and now winging. I've got a hybrid windfoil/winging board (JP FreeFoil) and an Axis foil setup with spitfire & HPS front wings and a progressive tail. As I progress on the foiling journey (and probably focusing more on winging than windfoiling) what kind of tails should I be downsizing to? They've got progressive, speed, skinny ranges plus others, in a ton of different sizes, and similar to the issue you note above, the "all rear wings" section doesn't contain the skinnies.
On tails, if you are up and riding comfortably, progressive THENskinny would be the upgrade path
The progressives are fun, go smaller to get better roll for snappier looser turns
Skinny tails are great for glide, very fast and efficient, even on the spitfires they seem to work
I'd say start near the bigger sizes on both, progressives can skip one size down each time, but skinny you'd be surprised how a bit smaller makes a big difference, so don't go too extreme on dropping down the sizes.
Final thing on Axis, get an Advanced+ fuse for sure!
