I can help with that. For the OPA350UA at U1, would you like three pin-compatible drop-in replacements for its existing footprint, or would you prefer three op-amps with similar specs (rail-to-rail I/O, low offset, single-supply) regardless of footprint?

Here are three 8-SOIC, single-supply, rail-to-rail op-amp replacements for U1, all pin-compatible with the existing footprint:

All three are drop-in-footprint replacements for the OPA350UA. If you need deeper performance trade-offs (noise, bandwidth, quiescent current), just let me know!
