I'll be curious what the wood flooring pros have to say on this question--particularly whether it makes a difference that the floors are engineered hardwood (since there are a limited number of times they can be refinished). I'm not sure there is a right or wrong answer to this question, but there are pros and cons either way. Two considerations:

1. If, in the future, you want to change the floors to a different material but keep the rest of the kitchen intact, it is easier to do this if the flooring doesn't run under the cabinets.

2. If, in the future, you want to renovate the kitchen and change the layout, but keep the wood floors intact, it is easier to do this if the flooring does run under the cabinets.

In our house, originally built in 1929, the original hardwood floors have been kept intact (though refinished a few times) through at least four different kitchen renovations over the last 85 years (some involving complete reconfiguring of the layout). This was possible because they run under the cabinets.

Personally, I would not worry about the installations of cabinets and appliances hurting the floors as usually the floors are covered during renovations if they are installed first.
