I wouldn’t personalize your resume for any company, nor do I recommend writing a personalized cover letter for any of them — you have no idea the skill set that will be valued by the person reading the resume, as they are an unknown random variable. I feel it’s just a time waste and there is no proof that this sort of thing is fruitful.
Also fuck leetcode. I’ve refused to do the leetcode and still gotten the offer to do an interview without it. Imo, we should all show some backbone and stop accepting all this superstitious mumbo jumbo as the accepted form of recruitment.
