How to move on from entrepreneur?

I started a business at 15yo, going well by 18 - there's been ups and downs and it's certainly been a fight, but I think it could be considered successful. I'm 28yo now.The business is in tech, based in the UK. I've made money in the very low millions over the last 10+ years, it's enough to pay myself and some family over the years but it's limited and not super successful. The company has never needed more than two or three employees.I want to move on and work with a team of colleagues in another tech industry. I'm not sure if it's just for the work-life change, industry change (within tech) or is it because the success of the company feels limited, It's unlikely to scale up anymore but unlikely to stop as is. It hasn't needed my time day-to-day for a while.I've been finding it hard to find another job for about 4 years, although I've only been half looking really if I'm being really honest with myself.I don't know how much to sell myself, or what to specifically sell myself for.What role? I done so many, and been successful in some. At what salary? I've been offered both end of the spectrum. I got second line interviews for a £38k role and another borderline consultant role at £130k but got neither of them in the end.How honest should I be? When I've talked about my genuine experiences I think it oversells me, I've been told it's too good to be true that I'm applying for XYZ role or they couldn't afford me or I'm not specific enough in any one role - other than generalist CEO by recruiters - but when I have applied for such top level roles briefly, my CV gets put through but the competition have much better company names on their history, although similar skills. I've gone for lower roles simply because I'm new to this I have little history outside my own business or consulting, and I'm not super bothered about the salary necessarily as long as it's fair for the role.I've tried being less honest by not mentioning I founded the company and shown a realistic breakdown of the roles I've done within, showing career progression within the company. This is got me the furthest, one company found out, others just didn't work out.The companies I've applied to so far tend not to go anywhere for an actual full-time job, but some have resulted in consultancy instead. This is what I've been doing most recently, but it doesn't give me the day-to-day team that I want.How honest should I be? Should I be fully honest but much more humble about my experience? I'm also not sure if I should be going into programming/software engineering (maybe senior level?) or into management, I considered Product Management and Business Finance also, assuming c-suite is out of reach due to my history.Edit: second attempt at posting, first time was auto deleted due to throw away karma.
