For citizenship, Ireland. For tax residency, UAE. Both are environments where English is the main language.
Ireland is the English speaking country that offers a pathway to citizenship yet doesn’t tax you to pieces.
You won’t get citizenship in any of the countries listed if you’re not living there the majority of the time, so might as well just go for the tax residency. UAE is possible with 90 days stay, but no treaty with the US.
Ireland does have a treaty, so may work out better. Have you considered the UK? There are ways to spend less than 182 days and maintain status, but︀ doesn’t lead to citizenship. For tax residency you’d need to spend the time regardless. UK︁ taxes are high but there are ways around it.
