Focus/Campagnolo cross bike as 1st bike

Hey, I’m looking to get into cycling and I found this used Focus cross bike that I’m considering.

The bike is 550 EUR which seems to be a fair deal, but I’m not sure if it’s the right fit for my needs as I don't know much about bikes. I need a do-it-all: for commute 2-3 days a week, 4-5 km each way + also would want to go for weekend rides with my friends 50-70 km gravel/road.

I’ve heard that 1×11 setups are great for gravel but may not be ideal for road rides if one wants a wider range of gears. I’m also considering possibly changing the crank for 2x? If that would work but I dunno if it makes sense/is feasible.

For reference I'm 185cm, 70 kg

Bike is described as: Focus Cro-Mo, double-butted with polished welds, size 58, groupset- Campagnolo Centaur 1×11, brakes- Shimano cantilever, wheels- DT Swiss 535 rims, Novatec A141SB + F162SB 32H hubs

Do you think this would work for my use case, or should I look for something else? Also would it need modifications for more road-oriented use or is 1×11 fine?

Thanks in advance for any advice!
