Look for 3 or 4 "independent Agents" in your area. Send out a request for bids note to each of them specifying your situation. Include the VIN numbers and your personal numbers. (you might call one first to determine all the stuff they want)
Conversely, do not fill out internet applications. You will be swamped with emails and phone calls for weeks or months.
Do the highest deductibles you are comfortable with. Be sure your home owners only covers the cost of reconstruction and demolition. You often don't need to insure the foundation, wells, septic, sewer lines, driveway etc... Our home is valued at around 230ish but our insurance is for 180ish. I don't anticipate replacing foundations and the basement slab. We are not in an earthquake prone area though.
(fires are the thing that get most homes, so be sure your smoke detectors are up to date and ask your local fire department to do a home inspection for free)
A typical MMM thing for auto insurance is to drive a 4K car and carry liability only. That is fine as long as you have a high coverage and most of your funds are somewhat shielded in retirement accounts. I would get the underinsured coverage.
