TL;DR - the better way is the way everyone intended MTP over a cable.
Not having an easily accesible place to view the current IP address is a bad UI/UX decision, but not ‘hiding’, yiu can if you so desire install a program to show the IP address.
As for browsing photos, you’re using an interface not meant for doing that (SSH), yes it will work and yes it is more convenient in the sense that you don’t need a cable to connect your phone to your computer but the purpose of SSH/SSHFS is not what you are using it for and it is not optimized for it thus when you browse windows will have to read whole files to generate thumbnails which it will then either save on the device or will be deleted when you disconnect thus browsing will be slow.
When using MTP over a cable you are telling both windows and the phone what you expect and the phone may even send its’ thumbnails instead of full size pictures.
As for wireless methods, other than them being potential serious security issues if you leave it on on public networks you could probably use a webdav server for this or a webserver that exposes your images.
As for your IP address changing you could set your router to reserve the same address for your phone.
