Churches are defiantly not immune to the financial strains caused by COVID, and for what you're looking for, there are plenty of good choices in the high/entry to mid level keyboards
It sounds like you need acoustic sounds and pads, so I'd personally would go with a Yamaha.
Since you already know how to use an arranger, how about one of the PSR models? Just because they have auto accompaniment, doesn't mean you need to use it. You're already familiar with the OS, and you know how to make registrations, which will be be a big time saver, trying to prepare with just a short time before a service.
Really any ROMPLER/ synth/workstation will do, but why spend precious time trying to learn something new? Just my thoughts.
