The best people I know do good in both local and global ways. It's not necessary to choose one or the other. I don't disagree with your examples, but I notice that they say nothing about donating money to World Vision or putting solar panels on your roof, for example. Replace these with causes you believe are good.
This might be unfair, but I'd summarise what you said as "living a charitable life, but only for people within 50km of your house", and I think it's fairly obvious that "living a charitable life, mostly for people within 50km of your house, but also you give $50 a month to an international charity and you try to generate a bit less carbon dioxide" is better for the world, better for you because you don't have to harden your heart, and wouldn't harm most people's ability to look after themselves.
I agree that it's possible to be too neurotic about this and do what Sam Bankman-Fried did. It's also possible to be a little better than average at caring for the world without much cost to yourself. I don't understand why anyone would have a problem with the latter.
