Inheritance of 1M, what to do?

A couple of months ago my husband (44) and I (36) were shocked to find out we inherited 1M and the estate has recently distributed the funds to everyone.

We owe 206k on our home, and have about 12k in debt, our cars are paid off and we aren’t sure what to even do with that kind of money.

We don’t plan on telling anyone in our family.

We plan to pay off our debt, he plans to continue working full time and I plan to continue doing social media and side gigs- basically we do not plan on changing our daily life. For now atleast.

What is the best way to invest this over the next 10 years at minimum.

Editing to add: we are not silver spoon children, we both grew up rather poor, we both make minimal money. This did not come from family- which is why we want to be smart about it. We also don’t want our kids being all “we’re millionaires” and become out of touch with reality.
