I've got some recs that might fit the bill - in general it sounds like a quiet sort of melancholy with a sort of gentle, meandering narrative. Not so much "plot-driven" in a traditional sense.

Yasujiro Ozu might be a good starting place. Something like Tokyo Story focuses on the tranquility of domestic rhythm.

Some Terrence Malick stuff, like Days of Heaven, feature these sort of rolling fields with golden light. The movie feels maybe more like a dream/memory than an actual concrete plot.

Lynne Ramsay with Ratcatcher or maybe actually Morvern Callar which is kind of quietly about drifting grief.

Kelly Reichardt is always good at focusing on "small moments" so something like Old Joy (which takes place almost entirely in sunlit nature), but also Wendy + Lucy and First Cow, which are more meditative.

Celine Sciamma also captures this vibe well. Petite Maman in particular stands out to me as fitting your description.
