I've had 5 DC go through this stage and 1 DS (yr8) still to go.
The eldest 3 are all in their 20s and didn't do as many GCSEs and didn't have as many options as they do now. All had to do maths, english x2, science x2, humanity, MFL, arts option, and then 2 more options.
DS1 chose design tech & business studies. He soon regreted choosing business studies! But had to stick it out. He did maths & 3 sciences at A level and studied engineering at university.
DD chose food tech & extra MFL. She did sciences and geography A levels and also went to university.
DS2 resistant materials & PE. Did maths and physics A levels and then did an apprenticeship.
DS3 now in year 12 had much more choice. Did
Maths, stats, 3 sciences, english , english lit, french, PE, Music. He chose not to do history or geography. Now doing maths and sciences at a level.
DS4 year 10 doing maths & stats, 3 sciences, english, english lit, PE, Design x 2. He chose not to do humanity or MFL. I was worried about this but he loathed french in years 7-9. He would have been in a lower group with others like himself, ie. not doing it through choice, no chance of getting at least a C grade, and being hard work for the poor teacher! Better to be realistic and let him choose something he will do well.
