The only mechanical uses of the the fiery blade are its unique action (make a melee spell attack, deal 3d6 fire damage on hit), and its ability to shed light. Since you can’t make a melee weapon attack with it, it isn’t a weapon, and thus can’t be used in conjuction with Green-Flame Blade.

Can you use haste, booming blade and Green Flame Blade?
What I want to do is a level 10 divine soul sorcerer and 2 levels in paladin. First round I cast haste then run away. Next turn I will cast booming blade with quicken to make it a bonus action. Then cast green flame blade. Finally I attack using Divine smite. Do these effects stack to make one really powerful attack?
Can a Paladins use divine Smite twice in one turn?
This means that you can cast seating smite as a bonus action, then use the attack action to attack once (or twice after level 5) and then use divine smite if one of the attacks hits. Yes, this can be a huge amount of damage in one turn, but it burns through your spell slots very quickly.
Do you have to hit before using thunderous Smite?
Only stipulation though is that you have to cast thunderous smite BEFORE you attack though, because AFAIK per the wording of the spell, it wouldn’t work if you hit before you cast it. And before you ask, YES you can use a bonus action before you attack, as it’s within the rules.
