Unfortunately not only have I not played a Monk I haven't bothered to read it as I don't particularly like them, not to mention that in our table the cool loot is extremely scarce so there's so I've never seen boots of flying and Combat, in general, is not my thing, get me in court or investigating and I'll be fine for the most part and I can figure out how to make a Wizard a way better scout than a Rogue although that mostly proves that the Bard is the best scout due to expertise + spells[footnote]Must mention that we play using the optional rule for Mana Points instead of Spell Slots.[/footnote] but get me in combat and I honestly prefer to run away, however with the one combat character I had I can only tell you one thing, always chop off the hand of your opponent, if he was a caster he won't be able to use Somatic components anymore and if he was a melee fighter with a magic weapon well he is both disarmed and unable to use the weapon as a 2 handed weapon.
However I may be of some help, what is your party's composition, do remember this isn't a single player game and true success comes from working together, for example we had a Wolf Totem Barbarian so positioning in a way that he gave me advantage but was also outside the range of my area of effect attacks was crucial for success, in any case as a melee fighter the best way to survive is to work together with the whole team and make sure everyone is positioned optimally and get the casters to give buffs and debuffs at the appropriate moment, I guess what I'm saying is that the key to success is asking for the advice of your party so that you can better coordinate and everyone can make the best use of their abilities, of course, I've learned that the hard way because in our table we like deadly campaigns in which Random encounters have the capabilities to give us a Party wipe and we focus a lot in survival stuff like hunting, eating, setting up camp and so on, plus we're a very optional rule heavy party.
