Like people not all bees are created equally as far as color, shape, and size. In fact, larvae and pupae will grow to the size of their cells. I once installed some longer drawn cells that were used for honey in a brood chamber and got longer bees. If you have curved wax foundation you may get short bees on one side and long bees on the other. I've seen it both ways which is why I'm mostly foundationless now.
If you look into the history of large cell foundation, humans took advantage of this to make a bigger bee able to forage certain flowers that smaller bees could not. This lead to standard 5.4mm foundation where bees typically draw 4.9 if left to do it on their own. Typically.
See if you can get a couple more pics from different angles. Head/eyes/mandibles don't look like a honey bee. Flat, extended abdomen resembles a leafcutter but they carry pollen on ventral side of abdomen. Possibly a type of 'miner bee', but that's just a guess after looking at some pics of bees native to your region.
