Wires are usually not necessary, you’d be able to tell if they seem crusty, cracked, or dry rotted. At the very least, it’s easier to do them later if you so choose.

You already took them out, that’s one of those things you should always replace “since you’ve already got it apart.” Those are toast anyway

If you drive in any sort of challenging conditions (rain/snow) it’s a night and day difference during spirited driving. If you simply daily your car and have a temperate climate, you’re less likely to see any benefit from high end tires. I wouldn’t use the cheapest available, but premium tires are typically overkill outside of a sports car or off-road vehicle.

I had a V6 mustang with cheap ass tires and that thing would slide all over the place. When I got a new car, I decided I’d treat it right with premium tires and it simply refuses to slide on me unless I really try

I’m hesitant to think the brake fluid is necessary for a 2020. If you’re concerned about it, get a second opinion.

Accept the CVT service, they’re all very particular systems that can’t take the kind of abuse traditional automatics could.

Filters and wipers you ought to DIY and learn as a regular maintenance item, you might need a screwdriver or a super cheap ratchet set at worst.

The mirage was at one point statistically the most dangerous car, as it had the most fatalities in accidents compared to other cars. I’d rather buy an actual coffin.
