It's a rule, not an exception.
Столица, встреча, наша - feminine.
Пейзаж - masculine.
Endings for feminine are ей/ой. Endings after ж, ш, ч, щ, ц depend on an emphasis. If the emphasis is on the ending, it is ой, like большой свечой. If emphasis is on any other part of the word, it is ей, like горячей кашей.
The same rule is for endings in musculine words after ж, ш, ч, щ, ц. If the emphasis is on the ending, it is ом, like врачом. If emphasis is on any other part of the word, it is ем, like пейзажем.
