I hold both UK and Irish passports as I was born in Northern Ireland. I have used my Irish passport for all interactions with the Spanish authorities since I arrived in Spain in 2019.
As you know Irish citizens can live in Spain with an Irish passport as the Republic of Ireland is part of the EU. So you’ve got the freedom to move and live in any other EU country, such as Spain. You only need to meet certain conditions to apply for Spanish residency.

Presumably you have researched the criteria to obtain an Irish passport if you don't already hold one. If not, you might find this link helpful:

You may also find the following link helpful as it contains a guide to obtaining a residence certificate as a EU citizen. Don't be too alarmed because it is issued by Age in Spain, the information applies to all EU nationals applying for Spanish residency:
