If your 105 stuff is old and you might upgrade it in the near future I would hold off to do all of it later.

Spend a little more and get an Ultegra 6800 or even Dura Ace 9000 instead.

Decide first what groupset level you would like to end up. Then you can check second hand market and slowly move towards it, getting parts as they become available at a good deal.

But just upgrading for the sake of upgrading or a "gut feeling", is probably a bad idea which will end up in wasted money and unnecessary intermediary upgrades. Try to go straight to your goal.

If you are new to cycling you really shouldn't spend any money on parts until you know your commitment level. I can promise that a 105 group can literally humiliate maaaany ultgra/duraace riders out there. If you get dropped or passed it's not because you have 105 but because the other guy trains harder.

Learn how to set up your bike. Read the installation manual. Do some checks. Make sure everything spins and shifts nicely. If you have any gritty bearings then they can be replaced or serviced. Clean your chain and lube it properly.

Are you looking for speed then work on your training/position.

Shimano groupsets can usually be moved to new frames quite easily. Whatever you upgrade to now could later be moved to a new frame and then you will need all your old parts to restore the old frame. So if you know your commitment level you can hunt for some duraace9000 parts and later use them on a new frame.

Best performance bang for the buck is ultegra and I can promise you that the differences to duraace will never lose you any race position unless it lacks maintenance.

Trust me when I say this. It’ll be easier and more satisfying to upgrade a groupset all at once

I'd opt for an UltraTorque chainset. Reliable, silent, narrow, nice, light.

I never had knocks or any suspicious sound with UT, the bearings last for ages (and can be changed for 5.5 USD in pairs. https://www.ebay.com/itm/2pcs-6805N-2RS ... 2095118535 .) . My mates with shimano chainsets always complain about clicks and noises.. :)

Your mates need to find better bike shops.

This is my personal opinion, but I for one think a casual rider replacing cranks when everything else remains the same makes sense, if the new one is indeed a powermeter.

Cranks get lighter as you spend more but they are not really an upgrade in terms of helping you go faster. They have to be pretty shite not to shift well. The chain rings on cheap cranks are worth upgrading for improved life. For Shimano kit, 105 us as good as it is gets. Dura ace is just lighter.
