Working FT past 67 - when to draw SS

Will be 65 next year and not considering retirement till at least 70. Layoff in mid 50’s & out of work for 3 years. With young family to support I had to draw on about 75% of 401k to not loose my house etc. Paid early withdrawal penalties too. Facing age discrimination, I retrained myself in cloud tech & cybersecurity and started new carreer. Worked way back to C-level and due to COVID our kids needed help. 1 now working FT the other has medical issues and we need to stay on employers insurance as long as possible to help our kids out and medicare coverage sucks. Am aware I’ll have to pay a higher fee when I do retire due to wages. Full retirement age is 67. Can you work FT past 67 and start SS at 67 ?
