best hardwood for first 3d milling attempt and end grain vs side grain

Not sure if its available there but Jelutong is a wood that is often used for hand carving because its very fine grained for a relatively soft wood. Its not very expensive, cuts lovely on cnc roters and is easy on cutters. Its pretty bland looking though but maybe you can try it.

I milled in all sorts of hardwood. Oak is a nice finish, and also walnut. but so far the best finish ive had has been from sapele. Once it got varnished it turned very dark and very glossy, the varnish brought out the natural glossy finish of the wood.

What size pieces are you looking for and where abouts in the country are you. If your close i might have a few bits i can give you.
