There's practically an entire genre (ok, small genre) that could essentially be called "sanitized historical period pieces". Westerns in particular have a history of cleaning up anything that would be considered negative, although the sensibility of what people would consider "inclusive" has changed a lot over time. High Noon and Johnny Guitar were both considered notably revisionist upon release. Wild Wild West, Shanghai Noon, and Jungle Cruise are more modern examples that are even more revisionist, and much more inclusive. Well, Jungle Cruise is modern, at least.
Its worth noting that revisionist history goes in the other direction, too. Gone With The Wind, for example, is very revisionist in the direction of pro-South, pro-slavery.
