Maybe I missed something... your income is USD 300k (so this will be your company income right?) in UAE the first AED 375k of profit (emphasis on the word "Profit" not income) are exempted, so about USD 100k.
remaining is USD 200k . I assume you have some expenses (corporate but also personal that you can invoice under the company like traveling, F&B,etc..) let's say USD 50k per year.
then are you are living in a country with territorial tax, you can pay yourself at least USD 150k per year which wouldn't be considered as exaggerated.. either as a freelancer (you send your invoice to the company) or salary (as director of the company for exemple).
at the end, as I assume you do not have any customers in UAE so
no VAT, you have absolutely no tax. even better you do not need to pay the fees to close the company and open a new one somewhere else. nor the struggle to choose a new jurisdiction that you don't know at all.
what I am missing? it looks like you are stressing out for nothing
