For the first time in 53 years of owning homes, my new house has a

I see prices can vary considerably but is a MERV 8 and MERV 8 regardless
of the brand?* Should I use MERV 8 or MERV 11?* We have no pets.

I see filters with MERV 11 rating from $9.95 ($7.45ea by a dozen) to
$14.50. Any real difference if they have the same rating?

Discount filters seems cheapest.

I use air filters and had never heard the term MERV so looked up your
question:

Prompted me to look at the filters I'm using and now see that they are
MERV 11. Don't know about price difference but sometimes filter may
collapse somewhat and more expensive filter might be sturdier.

I am no filter expert but IIRC if the MERV number is increased then possibly
the blower motor can overload. Research the info on your system to determine
the suitability.
Restricting airflow does NOT overload a blower motor. Restricted
filters restrict the amount of air moved REDUCING load on the blower
motor. Youknew that and forgot - right "tekkie"?
