I'd side with @Touloser. Being self-employed is a long hard road - my parents both do it and for many years their businesses weren't profitable and it can be very stressful. You don't have a safety net at all in times of sickness, and when you are at the point of having staff, the pressure of meeting payroll can be crushing when there are gaps in cash flow.
My advice would be to take a job in a field that does interest you and make as much money as you can. This will allow the the option to either a) start a business on the side and support it financially while it grows and b) stil provide you with opportunities to support women.
Some of my most satisfying moments in my job have been interviewing and employing women into junior roles, mentoring and supporting and teaching them. I've still managed to have a career that has fulfilled me - I didn't sell out completely for money, but I also had an eye on what I was taking home and the benefits package. Arguably not enough to be honest.
My other bit of advice at 24 is don't stay too long in your first jobs - loyalty tends not to be rewarded in many companies. Try and get promoted frequently and be in a job where you have a supportive boss who encourages you into opportunities. If you feel this is lacking, start looking for something else.
My final bit of advice is to negotiate salary (a recruiter can help with this) and to pay into a pension from day 1, preferably at a higher rate than the minimum, and look into salary sacrifice. The more you pay in while you're younger, the more work your money does for you without you having to do anything. It's harder to catch up later. Paying in an extra £100 a month from day 1 won't be noticeable if you aren't used to the money to start off with. Try and increase your contributions by 1% a year or a portion of your pay rises.
RE working from home - I reckon this will become more normalised now. Maybe not 5 day a week WFH roles, but definitely part of the week as companies look to downsize office space. It's definitely something you can negotiate at offer stage rather than exclusively looking for fully home based roles.
