What is the main difference between a lewis acid & base and Bronsted Acid & base?

Bronsted acids and bases accept or donate protons while Lewis acids and bases accept or donate electron pairs.

Bronstead acids and bases focus on what is happening with the protons. What is giving up and H+ and what is gaining an H+? Lewis acids and bases focus on the electron. What is giving up an electron and what is gaining an electron ?

Lewis acids and bases accept or donate electrons, respectively, while Bronsted acids and bases donate or accept protons, respectively.

Lewis acids/bases accept/donate electron pair. Bronsted acids/bases accept/donate hydrogen protons

Lewis acid is when accept electrons, while lewis bases donate electrons. Bronsted acids accept hydrogen protons, while Bronsted bases donate hydrogen protons

Are there examples of acids and bases that fit the Bronsted definition and not the Lewis definition and vise versa? Because the definitions use different subatomic particles as definers but aren't they often interchangeable as electrons are often connected to protons?

Lewis acid -> electron acceptor
Lewis base -> electron donor

Bronsted acid -> proton donor
Bronsted base -> proton acceptor

All Bronsted acids are Lewis acids, but the reverse is not true. This is the same for bases. Lewis acids such as BF3 are not considered Bronsted acids because by Bronsted's definition, acids need to be H+ donors.
