hello, and welcome to the forums.
i'd like to suggest three games that i think you might be interested in. [though i do realize this has been marked as "solved," it never hurts to have games that you can try if the initial few don't pan out.]
some of the games i'm going to mention are games you'll have to pick up from elsewhere. i'll try to point out where you can find them if that's the case.
right. onto the games:
heroine's quest: you mentioned wanting a female protagonist. well, heroine's quest is a game that's set up like that. you get a fixed character [in that it's a very specific lady in a very particular situation] but you get to choose how she powers up through the game. it's a little bit of a mixture between a rpg and an adventure game, too, which might make it a little more comfortable to play, since you know some of the conventions of the adventure genre and - thus - you can focus on the rpg elements in the game.
this game takes it's inspiration from hero's quest, which is the same style of game, but the protagonist is male. i bring up hero's quest, because you do need to be aware that the combat is a bit twitch-oriented.
heroine's quest can be had here:
http://crystalshard.net/?g=16 child of light: child of light is a BEAUTIFUL game that has graphics that sort of look a little like someone painted them. it - again - features a female protagonist and is completely turn based. one feature that might be a little of a turn-off is that everyone speaks in rhyme and that might not agree with you. however, it's turn-based, has a small party to manage, has a very simple set of skill trees that are easy to navigate and understand and has a very light crafting system.
the only minor problem it also has is that the adversaries you face sometimes do MASSIVE numbers for damage, so it can be a little tricky hanging in there while the fights get started.
child of light is an ubisoft game, so you cannot get it on gog. [which is a pity, it's a great game that i think more people should try.]
child of light can be bought here:
https://www.ubisoft.com/en-us/game/child-of-light/
you can also buy it through that-other-store-folks-don't-mention, but it'll force you to run ubisoft's launcher regardless [because ubisoft and friends don't care about convenience and the absurdity of running multiple launchers to get a game going, but that's a different issue for a separate topic.]
with all these games, i recommend watching at least a little bit of gameplay. to that end, i have [exhaustively] played through child of light, and you can find that playlist here:

while the combat is turn-based, this game does rely on button-presses for getting the "timing" of a hit just right. which veers it a LITTLE into a more frantic affair, but if you play with a controller, it won't be too bad. just be warned: one or two of the boss creatures can take a bit of doing.
costume quest can be had from gog and you can find it here:
https://www.gog.com/game/costume_quest i also did a [somewhat exhaustive] playthrough of this, too. again, i recommend watching a tiny bit to get an idea for what it is you're getting into so you don't regret your spend. you can find my playlist here:

i hope that you find a game that interests you and that is fun and i hope you enjoy the rpg genre.
