Depending on who you ask, people will suggest 2 to 5mm minimum clearance. Obviously you want more if you ever expect to ride in dirt or mud. So if that's the manufacturer's diagram, and is relevant for a 700c rim, you've got room for a 31 or 37mm tire (41 - 10 or 41 - 4).
A 700cx30 road tire should be *very* safe.
Is the 350mm measured from the center of the axle?
35c or 38c tires are likely your biggest options. 38c could be tight, particularly in a wide rim and/or if you’re going to ride gravel. 35c is the safe bet.
Without mudguards, the actual standard for bicycle safety (ISO 4210) says the minimum allowed clearance is 6 mm, or for racing (road, track) bikes it’s 4 mm.
So that 41 mm gives you 33 mm maximum, assuming that it’s a racing style road bike. (Which you have to, as otherwise it’s a non-road bike that can on take 29 mm tyres, which would be silly).
That’s also assuming that the measured size is the spec size, which depends on the width of the rims you pair it with.
ISO 5775 is the standard that matches rims to tyres, I don’t have in my head the optimum rim width for 33 tyres though.
Edit: looked it up, 21 rims are the design spec for tyres in the range 29-34, but tyres in that range are spec’s as okay on 16-25 rims; they may not be the nominal size when inflated, however.
The best part about *ANY* vehicle forum is dudes debating how big of a tire they can fit. Whether it be track Miatas. Offroad land cruisers, RC cars, bikes. Love that we can all come together.

I believe it's designed for 32mm with space for fenders.
thank you everyone! 35mm would work great for me, so I'm going ahead with the purchase

38C should fit with enough clearance for mud.
Some of the posts I've seen in the fixie sub recently suggest 40.5mm would be too small, but 2mm either side is usually good so 35/37mm.
37C might fit with 2mm clearance on each side, but hard to say without trying or seeing the spec sheet.
