Isekai: A Fresh Start

You lived your life in constant pain, always bedridden from a terminal illness. When you finally pass away, God gives you another shot at life in any way you'd like... You can ask to be a fantasy race like a dragon or demon, gain unparalleled power, get a special item to start off with or whatever else you can think of. I was watching 'Farming Life in Another World' and thought its beginning would make a good start for an open-ended scenario. Let me know if you have any advice for how to improve it.
