Katakana Name

My name is on the rarer side in English (Ryza) but I'm having a hard time figuring out the right way to write it in Katakana. I think r-ai-zah is the right way to spell it phonetically? All the Katakana lists I see have a ri/re type sound but not the more rye sound. How would I write my name in Katakana?

Maybe ライザー
?
Raizaa

What I could figure was similar but I don't have enough knowledge on Katakana works to know. These were what I found the mark at the end is new to me-
リェザ
リえザ
リイザ (saw a lot of places that listed this as Lisa?)

How is it pronounced? As in the English word “rye” then “za”?

Then I would say ライザ

Exactly that, yes
