Help to choose at home workout regimen with weights.

I am a beginner trying to start working out at home. Given my work and schedules, it is almost impossible for me to workout in a gym for 6 or 5 days a week. It is also becoming very hard to maintain consistency in my workouts. I'm young, but overweight and prediabetic with PMOS and insulin resistance. And I really do not have any idea with how to proceed with working out and what exercises I should do. Can anyone please guide me as to what exercises I could do on the daily, or rotate between days, and what weights I should use as a beginner? I will figure out the diet part, but it's becoming very hard to choose amongst different types of exercises.
