Let me just say something that may seem counterintuitive at first. I do not intend to contradict anyone, but rather just to give you my own opinion, for what it's worth.
For learning exposure and such, you do not want a forgiving film. Actually the foma is perhaps a bit too kind to beginners

You want a film that kicks your ass for every little mistake you make. Pardon my language.
When teaching students totally new to sheet film (and even film in general), I had them use.... polaroid. And the fuji equivalent. Why? It has slide-like very narrow exposure latitude. It is very unforgiving. If your metering is off a half stop or so, you see it for sure. if you can expose correctly for pola/fujiroid then you can shoot just about anything, including techpan and slide. Then you are a master
Now, instant film is rather pricey, so a lot of folks don't want to spend a lot of money on it. Fine, I understand. But just bear in mind that what makes a film optimal for a professional is not the same thing that makes it optimal for a student.
A student wants/needs an unforgiving film that teaches hard lessons, that forces the student to really sweat the little details like bellows factor and reciprocity and falloff. And above all... use a cheap film for starters because you will want to shoot a lot and try several variables.
N.b. we can tell you what variables will turn out to matter and which will not, but that is not what a teacher is supposed to do! You have to flounder a little bit on your own

Otherwise it's just a matter of following recipes rather than optimizing your own approach.
If you don't want to use a lot of film but want to learn how dev times and such affect the result, let me recommend shooting a fairly monotonous scene, and then cut your neg into strips and develop those for different times. In ~10 mins you learn everything there is to learn about how dev time affects the tone curve of your neg.
P.S. haha, yes zenrhino, indeed you can do this with roll film too! Even the superexperts resort to clip tests now and then.
