Let's start with how we use "will" and "would" as they relate to time.
Okay, I'll have to come back to this.
will - Use "will" for a spontaneous decision. - promise - close possibility
He said he would come back to this. - Use "would" for reported speech - time distance - the past - what someone said
I'd like to continue this discussion later. - Social circumstance - Use "would" to express politeness
I want to come back to this later. - Not as polite as "I'd like to come back to this later" but not necessarily impolite
I will like to come back to this. - Don't use "will like" to mean "want" in the same way we use "would like".
The idea of "want" is contained in the underlying meaning of both "will" and "would".
Would you remind me to come back to this? - more polite - social distance
Will you remind me to come back to this? - less polite - social closeness - but not impolite, especially if you use "please"
