I definitely think it’s worth trying. My wife is similar, I believe, as the rules and general way of playing were daunting, and made it not necessarily seem like something she would enjoy. We assured her that we would take it slow while she got the hang of it. She is still getting ideas for what’s possible, but she has her own character’s mechanics down, which is great. Best of luck to you!
As an old D&D player, I’ve been through multiple editions, and I honestly don’t get the hate for 5e. It’s not needlessly complex as 3 was, and not as brain dead as 4. It’s accessible to everyone, with enough complexity for those of us that liked 3. Pathfinder was fine, but trying it again after 5e is like watching extra work just appear on your table.
If you really want a good time, where the system is truly different for the better, then try Star Wars Force and Destiny. Best system around in my opinion.
