Where can I swap MATIC?

I'm interested in swapping my MATIC tokens for another cryptocurrency or fiat currency, but I'm not sure where to go. Could you recommend some reliable and trusted platforms or exchanges where I can safely and easily make this transaction? I'd like to make sure that the process is straightforward, that the fees are reasonable, and that my funds are secure. Additionally, I'm also curious about any potential limitations or restrictions that I should be aware of before proceeding with the swap. Could you provide some guidance on these matters as well?
