Absolutely agree on the OSB caution.
All wood absorbs moisture in humidity and will dry out indoors. That’s why it is advisable to get your kiln-dried wood and use what you have within a day or two of moving it indoors. It may want to move a bit, but if you have it securely fastened ( think framing nailer and/or screws) you will beat the wood into submission.
Consistent temperature and humidity would be a huge long-term plus🤔
