Since many of you are recommending I look into DM's Guild content, are you aware of anything that would serve as a tactical add-on to 5e? Something that would grant battlefield maneuvers to characters, revise monsters to give flavorful abilities in combat (as well as raising the effectiveness of solo creatures), and maybe provide guidelines to using terrain (this is what happens when you drop a chandelier, crack the ice on a frozen lake, etc)?
If not, is it "legal" for me to create something that can be used by the community?
Try 4e D&D instead?
I mean it's not impossible to do what you're asking as there are more 4e-ish 3rd party monster books out there, for example. And there are optional DMG rules for facing and flanking and some other things. There are 3rd party products to add classes like Warlord to 5e as well. But I am not sure patching the game to simulate those things better is actually a more enjoyable experience than just playing 4e which already does those things. 5e is fundamentally a change in direction and tone from 4e, and it's intentionally not many of the things you seem to want from it.
For you, that misses the mark, which is too bad. For the larger pool of players and DMs and fans out there, it's literally the best selling RPG ever, going back to the beginning of the inventions of RPGs. It seems to be a "hit" with an overwhelming majority out there. Which doesn't mean it should be a "hit" with you of course.
As for "guidelines to using terrain (this is what happens when you drop a chandelier, crack the ice on a frozen lake, etc)?" while you may find a 3rd party supplement for a series of such challenges, it will never be THAT complete. No game, anywhere, ever, is going to list that many details for rules. Even the crunchiest most hand-holding game is not going to go to that level of specifics. You will, on some level, need to be a DM/GM to play a role playing game. You're going to need to use some amount of general tools (DCs for difficulties of situations, comparable challenges, etc.) to adjudicate those things.
