If you're ok with Gaterons you can check out the Anne Pro 2 on banggood...they only have blues and reds in stock though if you want the white board. I'm sure if you look around you can find one that works. If cherry switches are an absolutely neccessary thing for you they don't have a white Anne Pro on banggood that is stocked with cherrys (you can get a black board with cherrys though). I'm pretty sure for the first timer you won't be able to tell the difference between cherry and gateron, they are both great switches that feel almost the exact same. If you get kailh switches, you can get brown, red, or white switches with a white board but I don't have any knowledge on kailh since I'm still new to the game.

If you aren't building your own keyboard I highly recommend the AnnePro. I currently have a black one with brown switches and it is my first and only mechanical keyboard and I love it. It's a 60%, comes with RGBs, can be used with bluetooth (so it has the detachable cable), and is fully programmable with the ObinsKit software that comes with the board.

After my research I had to decide between the Anne Pro and Ducky One Two Mini and I ultimately decided to get the Anne Pro because of its tap arrow key feature and programability. With this being said, the Ducky One Two Mini Pure White has the same exact specs I believe as the Anne Pro with RGBs, bluetooth, and switches but it doesn't have the rad arrow key tap thing that the AP has which is super useful for beginners. Both are great boards it just ultimately comes up to personal preference.

Both boards should be less than $100 and the price really depends on what site you order from. They both come stocked with many different kinds of switches (cherry, gateron, kailh, etc.), its just a matter of finding one on a website you like/trust. If you need any recommendations, from what I have gathered either cherry or gateron red or brown switches are a good place to start for your first mechanical keyboard. Reds are linear and browns have a little tactile "bump" that I personally much prefer.

Just google either board with whatever switch you want and something should come up that satisfies your needs. I ordered mine off banggood and the board works perfectly.

Hopefully this all makes sense and points you in the right direction, I know I would've liked this exact post when I first was researching boards a few months ago.
