Whole house protection is necessary, since almost everything these days contains electronics (even light bulbs). I replaced myself, in my Siemens style panel, double circuit breaker with whole house surge protected circuit breaker https://www.homedepot.com/p/Siemens-20-Amp-6-5-in-Whole-House-Surge-Protected-Circuit-Breaker-QSA2020SPDP/202562776
Perhaps I should add larger dedicated whole house surge protector, but I would leave it to electrician.
In addition my system is plugged into Furman Elite 20PFi conditioner with strong non-sacrificial surge protection.
