As a keen beginner, age 15; as soon as I got my own acoustic guitar for Xmas I tried to finger pick like Donovan
[ he was on the telly a fair bit in the early to mid 70s and I became a fan]..

Couldn't manage it, so have been a plectrum player ever since.

Never been too fussy about pick gauge or materials.
Most of the time I just used whatever I found discarded on stages and rehearsal room floors.
I never needed to buy a pick for over 30 years....

Last year I treated myself to a tin of Fender plectrums.

The mediums seem alright.
