Advice on creating a cohesive (first) album

Let me start off by saying I have been producing music for 5 years now (6 months on 6 months off for the first two and nearly every day the last 3), and feel I have (to an extent) found my sound. I have an idea of theme and topic(s) which relate/resonate personally with me, but I am struggling to figure out how to structure it, and how to make it not just sound like a compilation of different songs with no context, and make it a coherent narrative/ which feels connected throughout. I have a ton of music I haven’t released (in fact most of it is unreleased- I have a small catalogue, spread over two different artist profiles and a YouTube channel) I know this is not ideal for growth or solidifying my identity as an artist, and I have some stuff I think is pretty good that I didn’t publish for some reason at the time (oh I will come back and polish later or some other reason), which now feels disingenuous to include in said album, but also to release in general now, just due to its age and my disconnection from it. Any advice? Sorry for the disjointed thoughts
