what sort of banjo 5 string or tenor ? What sort of music and style of playing clawhammer /frailing would be an open back 5 string ,bluegrass style 5 string resonator Scottish/Irish trad 17 fret (Irish)short scale tenor
You can spend an absolute fortune on a banjo with a tone ring itself costing more than a decent guitar.
Have a look at https://www.andybanjo.com/
Deering Goodtime do some really decent entry models and beyond as do Goldtone, probably best to try a more entry level until you see if you are serious . You can then upgrade but keep first as your go to practice one. Eagle music of Huddersfield are worth looking at online
Alternatively you can get a 6 string "banjo" guitar but that not really the same learning the banjer

More likely Bluegrass. I was advised before to get a resonator and that it's easier to pick up than what I think. Is that the case?

Depends on the person as to whether it is easier to pick up. Bluegrass tends to be picked (with thumb pick and finger picks ) if you pick guitar I can see that it might not be such a leap.
I prefer clawhammer played with middle finger nail and thumb more "folky " and I tend to hear the tune more. The basic "bum ditty " strum ( I say "bum titty") is pretty simple to learn and you can play basic tunes quickly ,the 5th string can really fill out the sound and a simple tune sounds fuller and more impressive

BUM -- Play one of the first 4 strings with your middle (or index) finger. This is a quarter note.
DIT -- Strum with the back of your middle (or index) fingernail. This is an eighth note.
TY -- Pluck the 5th string with your thumb. This is an eighth note.

Sometimes with Bluegrass picking you hear bluegrass but have difficulty naming the tune. That said there are some brilliant players and I should practice bluegrass picking more.
The resonator throws out more sound and that suits that metallic picking and attack of bluegrass . You can of course play both types of music on openback and resonator ( some resonators can be removed and played open back). Resonator can be loud and often players will use a towel in pot of banjo to deaden the volume ( especially if you have a partner !)

Whatever you choose one of first banjer tunes to learn is "Simple Gifts" a Quaker tune . It is known to many as Lord of the Dance but of course the real words are "Stand free" in no time at all you will be sitting playing on a rocking chair outside the Pittodrie bar in your dungarees ,a fishing line and hook tied to your big toe ,telling varmints to git off yer property like the best of them
