Advice on built-in features for increasing vision loss

Hi

Need an expert’s guidance on a highly specific problem. I’ve been diagnosed with macular degeneration. While I’m still sighted, my sight is dropping fast. I’ll soon be completely dependent on screen readers, then voice typing.

Which OS, laptops, or tablets (Windows vs. Mac) have the best built-in features for these needs, and conversely, are there any I should completely avoid? Even bowers can make a huge difference! Appreciate any guidance thrown my way.

Cheers
