Cause of Frequent Appliance Failures in New House?

I just moved into a newly renovated house and have had what I think are electrical issues. I installed two security cameras - one in the front of the house and one in the back. The backyard camera has failed twice where it won't turn on and I'm now on my third, whereas the front camera is fine.

I also had a brand new vacuum cleaner blow out while in use, which tripped the electrical socket that my washing machine was connected to.

This morning my new Samsung dishwasher started blinking on and off by itself. I turned off the power to it for a minute and then turned it on again at the breaker, and now it won't turn on at all.

Now I have a problem with my Roku suddenly not working. It's only a year old.

I feel like this frequent failure of electrical appliances is due to some wiring issue although I can't really be sure since most of my appliances are fine (seemingly). I called a few electricians who said for $200 they will test the voltage out of my sockets, but couldn't really do much else.

I'm worried about having to replace thousands of dollars worth of appliances and looking for tips on any troubleshooting I can do myself?

Is it worth installing surge protectors in all of my sockets as a precautionary measure?

Could it be that the electrical box needs an upgrade? Or could it be something more sinister like faulty wiring throughout our new house?

Thanks!
