There aren't many other ACH options. There's Gemini, but they'll only serve people in the US, Canada, Hong Kong, Singapore, South Korea and the U.K.
There's also Uphold which has no mention of residency here -
https://uphold.com/en/legal/membership-agreement/ach but you hear very, very little about them on here at least. Occasionally I see mentions from people who use it regularly but rarely.
Lots of reviews there -
