Conditioner vs. Surge protector

Looking for a whole house surge protection.

Siemens seems to be the best company out there but its most recommended item (Siemens FS140 ) is out of stock everywhere.

Here ia an alternative:

Siemens FirstSurge Power 60 kA Surge Protector Bundle

What about this product? Looks like a circuit breaker with surge protection.

20 Amp 6.5 in. Whole House Surge Protected-Circuit Breaker

which product makes more sense? Circuit breaker has some MOVs. I understand this can potentially limit current.

Do any of the above limit current to my amp?

What about a power conditioner that has built in surge protection?

A spike of 300V can get through to your equipment unimpeded if all you rely is MOVs Also, watch for MOV's "expiration date" of a sorts - with every absorbed spike they wear out a bit until becoming essentially non-functional.
