Help! Stuck on what to do... (25 years)

Bare with me, this could be a long one
I feel genuinely stuck in life. Going back a few years, I did a Level 3 Extended Diploma in Applied Sciences. I also have AS levels as I did a year of A-levels course. Guys, my dilemma has always been what to study at uni as I feel like I have so many interests and I don't want to waste my shot at higher education by not doing something academically challenging and stimulating. Like I am also looking at the job prospects of a course. Add to that, my family are so cross with me for not completing my higher education and it's getting to me because siblings and other family members are getting to the stage where they're applying for uni/considering next steps after college and it's left me wondering where did I go wrong. I feel so so behind in life. I was so good academically.
I've always wanted to move out and start my own life really, that was the crux of it. But due to some personal issues, I've held myself back. I have had jobs since and tried different things like working in hospitality, events and warehouse and most recently working as a casual concierge/receptionist. And whilst I enjoy some aspects of the job, it's the same thing over and over and so boring and I feel like I can do so much better.
Lately, I've been considering uni because feel like time's running out but don't know what to study at university but I sure miss learning and college so much so currently thinking of doing an access to HE course (Humanities and Social Sciences). The thing is as mentioned before, I've got the necessary and required qualifications to get into university, and I have applied to a few universities (different courses; CyberSec, Econ and Data Science) and have received offers from them.
So like do I still need to do the Access course in this case? Should I just go to university since I have the offer? I feel so ashamed of my situation and I just want to do something that has structure, is challenging and that I will enjoy really.
Is there anyone else who has had a similar experience? How did you decide on what to study at uni? How did you find juggling it with work and life commitments?
Please guys share your thoughts and comments, I just know that I have to DO something otherwise it's the same cycle over again
