Dual-citizenship born British query - spouse visa

I am a born British citizen and have recently applied for Cypriot citizenship from descent (my family are all Greek Cypriot from Cyprus) both sets of grandparents born in Cyprus but my parents were born in UK. I should receive my citizenship by the end of October this month which will mean I will have dual UK-EU nationality.

I am in a long-term relationship with my boyfriend (been together 15 months) and we want to get married. He is a non-EU illegally in the UK. We have been living together since February 2018 and have bills and a tenancy agreement in both our names. I earn well over the £18,600 threshold and I am in full-term employment.

We are seeking advice on whether I am able to use my EU Passport (Cypriot) for his visa as a family member. I know that I am able to use my British passport for a spouse visa but I would like to know if we can apply via EEA route as an EU citizen seeking my non-EU spouse to reside with me in the UK as a family member. Any advice would be really helpful.

We plan to get married in either Cyprus or his home country soon.

Case law we have looked into is McCarthy, Zambrano, Metock and Lounes.

Many thanks!
