Sandpit for kids

I want to build a sandpit for my kids. After waching yt for ideas I decided to use 5"x10" (or similar if not possible) wood blocks and some lag nuts. The size would be 8ft x 4ft.
Nothing on the bottom, just weed fabric.
I'm asking for advice what exactly should I buy.
Timber/pressure treated/green ?
I know nothing about wood.
Which lug nuts?

I built one for the kids when they were little, many hours of digging ensured.

PT frame, no need to do anything to the bottom. But the key is getting a cover, keeps the debri, and animals out, keeps it clean! The mesh style that lets water pass worked the best. Buy the cover first, build the box to fit.

There are health risks associated with pressure treated wood and children, not huge for a sandbox but I'd avoid them given the options. I won't get into risks but here's a link to some information:
Pressure Treated Wood (mass.gov)

Consider PVC or composite boards, instead. They're generally a bit more expensive but you'll end up with a nicer and safer result. You can even find colors to give the sandbox a fun look. If you prefer wood, go with cedar or redwood.

In terms of connecting, I'd use 4X4 corner posts and some lag nuts, plus adhesive. You can also add triangle shaped horizontal pieces in the corners for seating which would add to ridgidity.

That is referencing the older PT materials, newer materials are safe. Plus our observation, the kids are in the sand box not even in contact with the box.

1. Cover? I was thinking about getting some plywood board on top or build one with fence pickets.
2. I will choose cedar if it is safe and reasonable priced.

Cedar is "safer" but will not last very long when in direct contact with the ground. Really unless your kids are going to chew on the wood I would not worry about using pressure-treated lumber.
