What's the best and cheapest way to move ERC20 tokens?

*EDIT: Found a solution and the entire process took around $16~18 worth of fees in total.

*EDIT 2: So, I first sent MATIC (Polygon Mainnet, not token version) to Binance as KuCoin's MATIC address was down during this time, then I exchanged MATIC to Stellar Lumens (XLM) and deposited it to Nexo.io. Apparently, Base Level users there get one free withdrawal per month. So I sent around $35 worth of XLM to that site as the minimum withdrawal for ETH there is 0.01 ETH. I converted my XLM to ETH, then sent the ETH to the address containing the tokens I wanted to transfer. Spent $10 for transfer fees and then sent the CGG and the remaining ETH to KuCoin. So in total, I only spent around $18 of fees through the entire process.

I've recently received some CGG (ERC20 tokens) in the Ethereum Mainnet for winning a small contest. Unfortunately, I'm rather reluctant on the current available means in moving it. I have little money to spare for fees (they're in a different network as well) so I am looking for the cheapest alternative. My goal is to at least have these tokens be moved to an account in a CEX which supports it (KuCoin), and before I'd send some ETH on my address to somehow move it. To summarize my current dilemma:

1. I wish to send ERC20 tokens to KuCoin
2. If possible, the entire process doesn't cost $20 or more
3. Is there a way to cheaply send ETH from Polygon Mainnet to Ethereum Mainnet without utilizing a CEX as I checked and each are asking around 0.0035 ETH for withdrawal fees?
4. Would bridging ETH from Polygon to Ethereum Mainnet cost less?

To explain further, I don't have the financial or occupational means that are usually available to those actively engaging in the Ethereum Mainnet, therefore, I'm seeking a cheaper alternative. Thank you, in advance for whoever can provide a cheap solution to my problem.
