How to restrict FindDistribution to real-valued distributions
If we ignore that feeding just 3 data points to a black box function that estimates a distribution is rarely recommended, there is a simple workaround that avoids obtaining complex numbers.
Look at ...

How to restrict FindDistribution to real-valued distributions
I think decimals cause it. The following works well.
d = TruncatedDistribution[{1, 7}, Rationalize[FindDistribution[{3, 3.4, 3.6, 4}], 0]]
CDF[d, 5] // N
