The only difference is culture. Even humans have variety in culture. So from my perspective what is the big deal what race you play? How are dnd humans boring? They are better than regular humans and you have exciting opportunities to take part in and roleplay.
Seems to me the only boring thing is lack of imagination.
I can only play third person games and would rather look at something other than a human if possible when playing a fantasy game since I see humans all day long. I have no issues with playing human in non fantasy games but I prefer playing elves when they are an option. Except Elder Scrolls games, for some reason most of my characters are Breton or Nord. :P I also won't play a short race because I am short in rl and it can make me quite grumpy at times.
Funny part is even though I would rather see something different to a human on my screen I would pick playing a human any day over anything with a tail. I have an occasional Tiefling character for DnD but I don't have to actually see the tail and I wanted to break away from always playing elf/half elf. Doubt I will be able to play him in BG3 unless I can find or make a mod to remove the tail.
As for the imagination part, it is the same to create a human as it is for almost anything else. Sometimes the race is important, sometimes not. I can easily come up with ideas even for races I will not play. For humans in DnD games though Darkvision is an issue. Don't want to have to play Warlock or waste a feat just to get this, and I don't like light spells or torches (usually play stealthy characters.)
