I would use Eaton for the service entrance unit, but most are similar. Use Eaton, or whatever the electrician usually uses.
Tripplite Isobar is a good point of use device, IMO.
Most of the transients in the house don't do anything. If you notice something in the AV equipment - audio pops, loss of picture, from a motor in the house, then a power conditioner may be of use. But, that is extremely rare.
The transients in the house do not damage the equipment, if it's built in the last 20 years.
The thing you are trying to avoid is damage from a lightning strike near your house.
There are things you can do to mitigate damage from a direct hit to your house, but it's more expensive than the equipment you're trying to protect. Think commercial broadcasting company or airport control tower - mission critical applications.
Series mode protection is good for transients, but they're not designed for large surges. If you're worried about lightning, I would skip series mode. In theory, a nearby strike shouldn't pass a large surge to the AV equipment, but that would be my primary concern.
