Answer 1

If you are establishing an analogy where:

• in one case you have several overridable methods;
• in the other case you have a Strategy interface with several implementations,

then the difference is the degree of coupling, which is very strong in the first case, whereas in the second case any foreign code can participate in your class's logic by contributing its Strategy implementation.
