Welcome to TRS~!
Common question with plenty of options.
There may be some direct posts on this so you would do well by using the search function on the site and play with that...someone might have a definite answer that suits your needs but usually there are slight variances that make every job a bit unique...like what seats you find as opposed to what you actually want...center consoles, seat belts, and bolting information can be very different...
The Tech Articles (link located at the top of the website page) are a fantastic resource that you will probably find to have information on just about everything...I have provided a link to the seats document and you will find more information at the bottom (blue links).

As a personal note I have installed many seats from many different vehicles...main thing is that the seat brackets are suitable and using the factory drilled holes is not only a safer bet but also reduces frustration levels immensely...
But as you will find, there are quite a few seat options that bolt right in from both other Ford vehicles and some non-Ford vehicles.
I preferred the Tempo seats for my application for a few reasons...number one being they were high back and comfortable enough to suit my needs for over 14 years...
They are not the best cushioned seats and do not offer much for performance with the stock seat...such as preventing you from sliding around in tight corners...which Rangers don't do well without some practice...so research...read...and ask again if you need to clarify things...there are actually too many details to list sometimes.
