Comparing MySQL and SQLite create table statements - mysql

Question

So I am trying to make an app with "code first" approach and active record ORM. I am willing to work with MySQL and SQLite (both) in this app. Here is how I am creating a database:
(this is a mockup table I came up with solely for this question)
$this->int("id", self::INT_MEDIUM)->unSigned()->primaryKey()->autoIncrement();
$this->string("hash", 64, self::STR_FIXED)->unique();
$this->enum("status", "available","sold","pending")->defaultValue("available");
$this->int("category", self::INT_MEDIUM)->unSigned()->defaultValue(0);
$this->string("name")->unique();
$this->text("descr")->nullable();
$this->decimal("price", 10, 4)->defaultValue(1.234);
$this->uniqueKey("store_np", "name", "price");
$this->foreignKey("category", "categories", "id");
and then my code generates CREATE TABLE statement for me, here are the results:
MySQL:
CREATE TABLE `products` (
`id` mediumint UNSIGNED PRIMARY KEY auto_increment NOT NULL,
`hash` char(64) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
`status` enum('available','sold','pending') CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL default 'available',
`category` mediumint UNSIGNED NOT NULL default 0,
`name` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
`descr` TEXT CHARACTER SET utf8 COLLATE utf8_unicode_ci default NULL,
`price` decimal(10,4) NOT NULL default 1.234,
UNIQUE KEY (`hash`),
UNIQUE KEY (`name`),
UNIQUE KEY `store_np` (`name`,`price`),
FOREIGN KEY (`category`) REFERENCES `categories`(`id`)
) ENGINE=InnoDB;
SQLite:
CREATE TABLE `products` (
`id` INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
`hash` TEXT UNIQUE NOT NULL,
`status` TEXT CHECK(status in ('available','sold','pending') ) NOT NULL default 'available',
`category` INTEGER UNSIGNED NOT NULL default 0,
`name` TEXT UNIQUE NOT NULL,
`descr` TEXT default NULL,
`price` REAL NOT NULL default 1.234,
CONSTRAINT `store_np` UNIQUE (`name`,`price`),
CONSTRAINT `cnstrnt_category_frgn` FOREIGN KEY (`category`) REFERENCES `categories`(`id`)
);
I executed both queries in phpMyAdmin and phpLiteAdmin, and both seemed to worked fine.
Here are my concerns:
For example, I didn't know I cannot use "UNSIGNED" with "PRIMARY KEY AUTOINCREMENT" in SQLite, which gave me hard time to figure out. Is there anything else like that I should be concerned about?
Even though both statements were executed successfully, are they going to work as expected? Especially the constraints in SQLite
Please check "status" column in SQLite, is it appropriate method to use as an alternative to MySQL's enum?
