Those are quite small for sandbaths I think, but it would probably get used as a toilet
They are ok but you maybe have room for something like a plastic ice cream tub (if you have one). Half fill that with sand and put a bendy bridge ramp up to it. Maybe best to have it on top of the substrate - if it's on the shelf they can kick sand out through the bars.
I would recommend getting a potty litter tray and the sand first - you can add a sand bath later maybe. I found our hammy used the litter tray for both. He pee'd (very carefully) in the very back corner then sat in the front for a wash and even rolled in it a bit.
The enclosed ones can be a pain to take apart and put back together. I had this one which was easy to take in and out and empty and big enough but not too big. You wait to find out where Brian chooses to pee (it's usually a corner of the cage) and then put it there with sand in - and maybe a tiny bit of his pee'd on substrate on top so he knows it's still his pee corner.

Then you'll get to see if he likes sand or not before giving him an actual sand bath. Our Syrian hated sand lol. It does soak up the pee well though.
If you're looking for a couple of extra basic toys, then bendy bridges are always popular. They can be bent to make a tunnel, a bridge, or a ramp. Putting one over the house door gives a ramp onto the house roof and makes the house dark inside as well.
A couple of these maybe

These were our hammy's three favourite things

Large sputnik - hangs from the roof - next to a shelf is best so they can get into it and with some fitch in it.

Be careful though - it can get expensive buying lots of toys! A couple of bendy bridges and a kitchen roll inner tube and half an egg box would do at first
Any toys you buy need to be checked carefully for sharp bits, splinters or nails sticking out (usually the wood ones). Sharp bits can be snipped off.
They always need something to chew on, like a chew stick as their teeth grow constantly and chewing hard things is the only thing that keeps their teeth the right length or they can grow really long (unlikely to happen as long as there is something to chew).
These whimzee toothbrush chews are loved by hammies - sometimes it's so special they will drag into their house to keep it safe

You can also stick sunflower or pumpkin seeds between the bristles to make it fun for them - and watch him getting them out.
I wasted a lot of money on rubbish toys that were either too small for a Syrian, dangerous, or fell apart after two days. Most of the things you see sold as hamster toys are only big enough for dwarf hammies really. Rat sized toys are better for Syrians and they can't get stuck in them. It's easy to get carried away looking at all the cute hammy things lol. They all have their own little personalities, and ours was quite laid back and a bit lazy even - he wasn't the slightest bit interested in toys unless they had food stuck on them or were round hides or tunnels to run through. So really they like hidey places, tunnels and lots of substrate, food and their nest. It can make the cage look fun to have something colourful in though. I had one of these

The wood blocks slide up and down so you can put treats like a nut or pumpkin seed in between them and the bell rings when they eat off if. It's best hung over the shelf I think because the ring at the bottom is quite small - if a hammy got a foot stuck and it was high up they can end up hanging by a broken leg. I had mine higher up so I swapped the ring for a keyring ring which was bigger
Viovet also sell the hyacinth tunnel and the rainbow bridge and bendy bridges as well, plus the chinchilla bathing sand, so getting most things from one place can save on postage. They deliver quite quickly and postage is reasonable but I find it hard to find things on their website sometimes.
Only thing is - you don't want to be changing a lot of things once he moves into the cage as it could stress him while he's settling in. Adding one or two new things is ok but not rearranging the cage. But you can add new things over time and just start with a couple of toys and chew maybe
If you only get one toy I would get one of these - it's big - would fill up a lot of floorspace in the centre and makes a good tunnel to run through and climb over with a natural texture. They can be a bit mucky and dusty when they arrive occasionally and need brushing out a bit - maybe.

They have artificial dyes which aren't good for hamsters,and the ingredients are just as easy to add one at a time as individual treats rather than having to rely on artificially dyed sugar-loaded junk if your main food doesn't have some of them!
