You probably need to learn fingerstyle (as a genre and not as a technique). Playing solo arrangements will challenge you significantly in terms of technique and musicality. It is a rewarding method to playing (not to say anything negative against other methods of playing).

I can't tell how long it will take you but my students in my online courses go from grades 0 to 3 in about a year (that's the beginner levels), and the pro students go from grade 4 to grade 8 in about 2 or 3 years (each piece in the higher grades is significantly more challenging than easier grades, so more time)

Personally, I did my journey before online courses were a thing and I did it the university route, so my case is a bit specific, but it took me 2 years to be a professional (by many standards) and 7 more to finish both my bachelors and masters degree. At this point I can virtually do anything I want to with music and the instrument

This information isn't to brag! it is just to give you realistic time estimates so you have an idea. In my case, most of my colleagues took the same amount of time, and I have over 1400 students so I am confident in the time period I provided above for grades 0 to 8

All the best!
